Abstract
Parents are often the first to detect the initial signs of anorexia nervosa (AN) and take necessary measures to ensure that their children receive appropriate treatment. The evaluation of AN in adolescence is complicated by taking into account the tendency to minimize and deny the symptoms by adolescents, and the difficulty of parents in detecting the main symptoms. We compared the adolescent and parent scores on measures of disordered eating at initial presentation. The sample consisted of 62 adolescents diagnosed with AN, who attended an eating disorder children’s unit. Adolescents completed the Eating Attitudes Test (EAT-40) and their parents the Anorectic Behavior Observation Scale (ABOS). The questionnaire data were collected as part of the routine clinical practice and were obtained from clinical notes. The findings indicate no significant correlations between the EAT-40 and ABOS scores, or between AN subtypes according to parent observation of symptoms. There were significant differences between parents, with mothers reporting higher scores than fathers. This study highlights the importance of psychoeducation for parents on the early signs of AN, in order to improve recognition and diagnosis at initial assessment of their adolescent children in the early phases.
Introduction
The clinical evaluation of adolescent mental problems requires several informants (Comer & Kendall, 2004; Kendall & Flannery-Schroeder, 1998). Gathering information from multiple informants can provide a comprehensive and balanced evaluation of a subject’s behavior, experience, or functioning, which allows for a more accurate clinical picture (Jepsen, Gray, & Taffe, 2012). However, there is often a discrepancy between informants, especially between parents and children (Achenbach, McConaughy, & Howell, 1987). Generally, a low-to-moderate concordance has been found in the multi-informative psychological evaluation of the adolescent (De los Reyes & Kazdin, 2005).
Most previous studies conclude that there is greater parent–child agreement when evaluating externalizing symptoms (observable behaviors) versus internalizing ones (cognitive, mood, and physiological elements; Seiffge-Krenke & Kollamr, 1998; van der Meer, Dixon, & Rose, 2008; Yeh & Weisz, 2001). For example, Salbach-Andrae, Klinkowski, Lenz, and Lehmkuhl (2009) found a poor to low agreement between parents and adolescents in internalizing disorders and a moderate agreement on externalizing ones. In their study with a clinical sample of adolescents, parents tend to emphasize the severity of the difficulties, while adolescents tend to minimize the symptoms. A study by Cantwell, Lewinsohn, Rohde, and Seeley (1997) with a total of 281 parents–adolescents found an excellent agreement in the behavioral disorders and central symptom of anorexia; a good agreement in separation anxiety disorder, oppositional-challenging disorder, attention deficit hyperactivity disorder, substance abuse/dependence, and central symptom of bulimia; and poor agreement in major depression, dysthymia, anxiety disorders, alcohol abuse/dependence, bipolar disorder, and obsessive-compulsive disorder. In their study, they concluded that including parents in the evaluation of the adolescent is useful in the evaluation of externalizing disorders, but if a single informant has to be chosen, the adolescent would be a better choice.
Discrepancies have been found in the perceptions of fathers and mothers about the problem of their child. Achenbach et al. (1987) concluded that the agreement was greater between fathers and mothers in externalizing versus internalizing symptomatology, with mothers reporting the greatest internalizing problems. Duhig, Renk, Epstein, and Phares (2000) conducted a meta-analysis focused on the inter-parental agreement. They found moderate correspondence between mothers and fathers in ratings of internalizing behavior and large correspondence in ratings of externalizing and total problem behavior. In general terms, the research suggests that mothers report more internalizing symptomatology than fathers (Grietens et al., 2004; Treutler & Epkins, 2003).
There is a difference found in studies with community samples versus clinical samples (MacLeod, McNamee, Boyle, Offord, & Friedrich, 1999). In community samples, adolescents report more internalizing and externalizing behaviors than their parents. However, in clinical samples, adolescents report less externalizing and more internalizing symptoms than their parents. These results highlight the importance of the environment, the motivation of the child, and the type of problem evaluated in the completion of self-report inventories (Smith, 2007). The research suggests that the discrepancy between parents and children can influence the evaluation, classification, treatment (De los Reyes & Kazdin, 2005) and prognosis of adolescent psychopathology (Ferdinand, van der Ende, & Verhulst, 2006).
Anorexia nervosa (AN) is an eating disorder (ED) that usually onsets in adolescence (Rohde, Stice, & Marti, 2015). According to the American Psychiatric Association (APA, 2013), it is determined by a distortion of the body image, refusal to maintain an equal weight or above the normal minimum value considering age and size, presence of amenorrhea, and intense fear of weight gain, which leads to adopt inadequate strategies to prevent increase in the form of excessive physical exercise and food restriction, called, in this case, restrictive anorexia nervosa (AN-R). If it is also associated with food binges and/or purging behaviors such as self-induced vomiting or overuse of laxatives, diuretics, or enemas, it is called anorexia nervosa binge-purge subtype (AN-P).
The beginning of AN is almost imperceptible, and the first signals may seem as a form of self-discipline and willpower that does not catch the attention of those around them. In addition, psychological aspects that contribute to the disorder, such as emotional problems, low self-esteem, tendency to extreme perfectionism, overvalued ideas of the body or body image, can go unnoticed (Lacoste, 2017). Furthermore, people who suffer from the disorder usually adopt a secret attitude, hiding eating disturbances and body shape; for example, using loose clothing, avoiding certain situations of exposure of their body (e.g. going to the pool or to the beach), or social meetings in which they may be forced to eat, which leads them to lying, deception, or contradictions. The minimization of symptoms and negation are frequent in AN (Starzomska & Tadeusiewicz, 2016), especially in the early stages of ED. It has been suggested that although there are behavioral symptoms in AN, such as self-induced vomiting, diuretic and laxative misuse, and excessive exercise, the secret and private nature of ED behaviors means that these can be considered as internalizing conditions (Mariano, Watson, Leach, McCormack, & Forbes, 2013).
In adolescence, parents, and other authorities such as educational centers, are one of the key detectors of the first alarm signals of AN. They can take measures such as seeking professional help for their children to avoid them from developing ED and receiving appropriate multidisciplinary treatment. Thomson et al. (2014) concluded in their qualitative study that parents require early advice and support to confirm their suspicions that their children might have AN, and suggested that they approach the Internet for guidance, and that awareness of useful and accurate websites could reduce delays in help-seeking. Rome et al. (2003) and Nicholls and Yi (2012) recommend including the family in the initial assessment of the disorder, from the early stages of diagnosis, as well as in the treatment process. In addition, studies such as those of Couturier, Lock, Forsberg, Vanderheyden, and Lee (2007) and Hail (2018) indicate the important role that parents of children and adolescents can play in identifying restrictive symptomatology and evaluation of AN. On the other hand, it is known that the prognosis of this disorder improves if it is detected and treated early, and that one of the predictors of a low response to the treatment of AN is precisely the longest duration of the disease before being treated (Weigel et al., 2014).
Reviewing the scientific literature on the concordance between parents and children on ED symptoms, Cantwell et al. (1997) in a community adolescent sample (14–18 years) demonstrated excellent parent–adolescent agreement in the key indicator of AN, that is, refusal to maintain an equal weight or above 85%, considering age and size, but only moderate agreement in the key indicator of bulimia nervosa (BN), that is, frequent binge eating. The study carried out by Steinberg et al. (2004) on a sample of children from 6 to 12 years old found no agreement between what was reported by the parents and the children. Parents reported more frequent binge eating than their children, while the children reported greater compensatory behavior than their parents. On the other hand, Pendley and Bates (1996) examined the agreement between 319 mothers and daughters aged 12–15 years in food symptomatology. The results indicated that the mothers underestimated the symptoms that their daughters referred, emphasizing the difficulty of detecting the food symptomatology.
In clinical samples, Couturier et al. (2007) conducted an investigation on 117 children and adolescents diagnosed with EDs (AN, BN, and ED not otherwise specified). In the AN group or with unspecified symptoms of a restrictive type, the scores of the children were significantly lower than those of their parents in the food restriction and weight preoccupation. Parent–child concordance was low with respect to AN. The results suggested that patients with AN could underestimate or not report their own symptoms. In the BN group or with unspecified symptoms of bulimic type, the children scored higher than their parents in restriction and shape concern. Patients with BN reported better representation of their symptoms than their parents. They explained that parents might perceive less binging and purging behaviors, and better restriction and excessive physical exercise, and therefore underestimated the bulimic symptoms presented by their children. In conclusion, they emphasized the role of parents in the evaluation of AN.
Another more recent study conducted by Mariano et al. (2013) in a sample composed of 619 parents and children found a low to moderate agreement between informants. The parents identified the presence of behavioral symptoms in their children (except for excessive physical exercise), but they referred to the increase in frequency of these symptoms. Children below 12 years of age reported less anorexic symptoms than their parents, with the reverse effect occurring in adolescents. It was a good concordance between parent and youth scores for AN presentations, but with no support for the idea that youth with AN presentations would identify less-elevated psychopathology, as was the case in Couturier et al.’s (2007) research.
There is no agreement in previous studies about knowing which of the informants are more reliable, parents or children. Smith (2007) proposed a decision-making based on the child’s age (younger vs older), setting (inpatient vs outpatient), and problem type (internalizing vs externalizing). Karver (2006) proposed three components, salience to the parent, salience to the child, and observability/willingness to report, uniquely to prediction of agreement. Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-4; APA, 1996) prioritizes youth information in the evaluation and diagnosis of ED; however, Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) widens this criterion to include behavioral observations by other significant people, such as parents, to influence diagnosis and clinical formulation (Mariano et al., 2013).
Since the results in previous studies are contradictory, we wondered if parents could be accurate detectors of the eating symptoms that their children suffered from, or, on the contrary, these symptoms were not adequately detected. Therefore, the objectives of this study are as follows:
To determine whether the perception of parents on anorexic symptomatology correlates with the eating symptoms reported by their adolescent children diagnosed with AN. We hypothesized that the greater the symptomatology referred in children, the greater the observation of symptoms by their parents.
To examine whether there are discrepancies between mothers and fathers on the perception of anorexic symptomatology. We hypothesized that mothers will identify more anorexic symptomatology than fathers.
To analyze whether there are differences between adolescents diagnosed with AN-R and those diagnosed with AN-P, based on the parents’ observation of their anorexic behavior. We hypothesize that parents will perceive the purgative symptomatology less than the restrictive symptomatology.
Method
Participants
The sample is composed of 62 patients, 90.3% female and 9.7% male, aged between 13 and 17 years (M = 14.81, SD = 1.377). They attended the ED children’s unit at Lozano Blesa University Hospital in Zaragoza, Aragón, Spain, between 2015 and 2017. The ED unit is the only public unit in the region (Aragón), so all patients in the unit are referred by the pediatrician for suspected ED. The ED unit has a multidisciplinary team composed of a psychiatrist, a clinical psychologist, a nurse, a social worker, and an administrative officer. In the unit, evaluation and diagnosis, medical and pharmacological treatment, individual and group psychological treatments, and family and social intervention in people with EDs are carried out. There are two types of treatment: outpatient program (patients with their family members attend outpatient consultations with psychiatry, clinical psychology, nursing, or social work) and hospitalization (patients are admitted to the hospital’s brief infancy-juvenile unit of the hospital itself). On reaching the unit, the administrative collects the sociodemographic data. The clinical psychologist or the psychiatrist conducts the evaluation interviews for both the children and their parents. All the patients who come to the unit, between the first and the second day, complete a psychometric evaluation protocol that includes evaluation of the intellectual capacity, presence of anxiety or depression, and ED symptoms (this includes the Eating Attitudes Test (EAT-40) and the Anorectic Behavior Observation Scale (ABOS)). The clinical psychologist is responsible for applying the protocol and correcting the corresponding questionnaires/scales, and making a brief report with the results and the diagnostic impression. Psychiatrists and clinical psychologists, through diagnostic interviews and psychometric evaluation, finally determine the diagnosis of each patient according to DSM-5 (APA, 2013) and the individualized treatment plan.
Instruments
EAT-40 of Garner and Garfinkel (1981) was adapted and validated in the Spanish population by Castro, Toro, Salamero, and Guimerá (1991). It evaluates the presence of abnormal eating attitudes, especially those related to the presence of restrictive food patterns, impulse to lose weight, and fear of weight gain, distributed in three factors: diet, bulimia and concern for food, and oral control. It is composed of 40 items, with a Likert-type response pattern of 6 points, from 0 (“never”) to 6 (“always”). The scores range from 0 to 120, with an established cutoff of 30 points (Toro, Castro, García, Pérez, & Cuesta, 1989).
ABOS of Vandereycken (1992) was validated in the Spanish population by Martin et al. (2013). It is a self-administered instrument and is completed by the patient’s parents or partner. It evaluates eating symptomatology and is considered as a useful tool for the screening of changes in eating behavior, mainly anorexia and bulimia. It is composed of three subscales: eating behavior, related to weight and food and denial of the problem; bulimic behavior; and hyperactivity. It consists of 30 items, with three response possibilities: “yes” (2 points), “no” (0 points), and “?” (1 point). The scores range from 0 to 60 points, with 21 being the cutoff point. It shows good internal consistency with Cronbach’s α of .81 (Martin et al., 2013).
Procedure
This is a quantitative, retrospective, descriptive, and transversal or static design because we are interested in studying the phenomenon at a specific time.
This study is a part of a larger project called “Attachment, body dissatisfaction and quality of life in adolescents with eating disorders,” in which 260 patients were selected and whose final study has not been completed yet. Ethics approval for the study was obtained from the Hospital Universitario Lozano Blesa de Zaragoza.
The results of the questionnaire scores were retrospectively collected from the clinical histories, since the data are a part of the routine clinical practice of the ED unit. One of the researchers was responsible for reviewing all the clinical histories of the patients who were attending the unit at that moment. Of approximately 300 clinical histories reviewed, 62 patients met the inclusion criteria detailed below. For methodological and homogenizing issues, the following inclusion criteria were established: (1) patients between 13 and 17 years, (2) meeting the diagnostic criteria of DSM-5 (APA, 2013) for the diagnostic category of AN (both AN-R and AN-P), and (3) completing the questionnaire for the patient and at least one parent. The results of the questionnaires, together with the information of the diagnosis, sex, age, population, and school, were collected by assigning a code to each patient so that the confidentiality of the information and anonymity were completely guaranteed.
Data were analyzed with the Statistical Package for the Social Sciences (SPSS), Version 19. Depending on the nature of the variables, we performed descriptive statistics, Pearson’s correlations among the main study variables, Student’s t test for one sample, and another for independent samples.
Results
First, we carried out a descriptive analysis of the sociodemographic and clinical characteristics of the sample. All patients are diagnosed with AN: 71% of AN-R and 29% of AN-P. As for the place of residence, 45.2% were from a rural location, while 53.2% were from an urban location. All were students, with 66.1% attending public school compared with 33.9% attending private school (see Table 1).
Sample demographic and clinical characteristics (n = 62).
We checked the normality of the sample with the Kolmogorov–Smirnov test for a sample. The results are as follows. For the EAT-40 test: Z Kolmogorov–Smirnov = .902, p = .390; ABOS mother: Z Kolmogorov–Smirnov = .719, p = .679; ABOS father: Z Kolmogorov–Smirnov = .732, p = .657. The sample is normally distributed, so parametric tests are used.
A descriptive analysis of the main results of the questionnaires was carried out (see Table 2). Other relevant data were that 98.39% of the mothers of the patients completed the ABOS questionnaire, compared with 87.10% of the fathers.

EAT: Eating Attitude Test; ABOS: Anorectic Behavior Observation Scale; SD: standard deviation.
Considering the cutoff score equal to or greater than 21 in the ABOS questionnaire, 63.9% of the mothers observed anorexic symptomatology in their children, compared with 36.1% of the mothers who did not make this observation. As for the fathers, 52.7% did appreciate the ED symptoms, while 47.3% did not. The average of both parents exceeds the cutoff point by 1–3 points (ABOS mother: M = 24.52, SD = 9.64; ABOS father: M = 22.69, SD = 8.93). Regarding the cutoff point for EAT-40, a score equal to or greater than 30, 59.7% exceeded the cutoff point, while 40.3% did not. The mean of the scores exceeds the cutoff point by 12 points (M = 42.37, SD = 25.79).
To respond to our first research objective, Pearson’s correlations were analyzed between EAT-40 scores completed by adolescents with AN and the ABOS answered by parents. The results, as shown in Table 3, evidence that there are no significant correlations between the scores of the EAT-40 and the ABOS completed by mothers (R = .214, p = .098) or fathers (R = .151, p = .276). However, there are positive correlations in the scores of the ABOS between both parents (R = .842, p < .05).

The correlation is significant at .05 level (bilateral).
To test the second objective of the investigation, we first performed a chi-square test based on whether the fathers and mothers exceeded the cutoff point in the ABOS. The results are χ2(32) = 58.832, p = .003. There are statistically significant differences between both; the percentages are different between the fathers and mothers. Student’s t test for one sample was conducted with ABOS scores according to mothers and fathers. The results indicate that there are significant differences between the two with p < .01. As shown in Table 4, mothers obtain higher scores (M = 24.52, SD = 9.64) than fathers (M = 22.69, SD = 8.93).

To respond to the ultimate objective of the investigation, Student’s t for independent samples was performed in order to know whether there were differences between patients diagnosed with AN-R and AN-P, regarding the observation of symptoms by their mothers or fathers. The results evidence that, assuming equal variances, there are no significant differences between the AN subtypes both in the observation of symptoms by mothers (t = .534, p = .595) and fathers (t = .414, p = .680). See Table 4, which shows the main statistics of this test.
Discussion
The first objective in this study was to determine whether the perception of parents about anorexic symptomatology correlated with the symptomatology reported by adolescents diagnosed with AN. The results indicate that this agreement does not happen taking the sample as a whole; that is, higher scores in eating symptomatology reported by adolescents with AN do not imply that parents detect greater anorexic behavior. This result is in line with the research of Couturier et al. (2007) but is in contrast to the study by Mariano et al. (2013). Taking into account that the EAT-40 is a screening test, it is striking that almost half of the patients diagnosed with AN do not report enough food symptoms to exceed the cutoff point of the test. In fact, all the patients should have exceeded the cutoff point, since they all have AN diagnosed by specialists. On the other hand, a large proportion of the parents do not detect the anorexic symptoms of their children; the mean of the score being slightly higher than the cutoff point (1–3 points). This could be explained by the tendency to minimization and denial of symptoms by adolescents suffering from AN as shown in the study of Starzomska and Tadeusiewicz (2016), as well as the propensity to concealment of eating pathology, which makes it considerably difficult for parents to detect the first signals of alarm and be aware of the severity of the disorder.
The second objective was to examine possible discrepancies between parents regarding the observation of anorexic behavior in their children. Although among them, they obtain a significant positive correlation in their scores, that is, the greater observation of anorexic behavior in their child by one parent implies a higher score in the other; differences are observed between the two. Mothers see more eating symptoms than fathers. This result confirms our starting hypothesis. Although there are no previous studies that compare the perception between fathers and mothers in ED, this result would support previous studies that conclude that mothers are better at perceiving the internalizing symptoms of their children (Grietens et al., 2004; Treutler & Epkins, 2003), taking into account our perspective of considering AN as an internalizing disorder due to the special conditions already mentioned. A possible explanation of this fact could be that, despite the progress that is being made in today’s society to promote greater reconciliation in work with family life in the female sector, women still assume the major role in bringing up their children and spend the most time with them, and therefore can better detect the changes that their children suffer.
The third and final objective was to analyze whether there were differences between adolescents diagnosed with AN-R and AN-P with regard to the observation of anorexic behavior by their parents. The results show that this difference does not exist; that is, binges and/or purging behaviors do not make anorexic behavior more detectable by parents. This is contrary to our predictions, because although previous studies compared AN with BN rather than subtypes of AN, we expected that parents would perceive binges and/or purging behaviors of their children less, as Couturier et al. (2007) had concluded. This result must be taken with great caution since the ABOS questionnaire focuses mainly on the observation of restrictive behavior and there is only a single item that refers to self-induced vomiting and none referring to binge eating.
This study provides a novel way to compare the observation done by parents of the eating behavior in the subtypes of AN in a clinical sample, since we have not found any current study that investigates this aspect. On the other hand, we have been able to examine the differences in perception between fathers and mothers that had already been detected in other mental disorders but not in ED. It must be borne in mind that the ability of an informant to provide meaningful information about a mental disorder can be influenced by several factors such as the environment or the implicit characteristics of the parent and the subject (Wingenfeld, 2002). In the case of parents, they may not report their children’s problems to avoid being stigmatized or to conceal a possible intra-family conflict (Grills & Ollendick, 2002). It can also be influenced by the parent’s own psychopathology (Kelley et al., 2017) that they themselves have suffered or are currently suffering from ED. In the case of adolescents, factors such as age, type of problem, and demands of the assessment setting are significant aspects to be considered by the clinician (Smith, 2007). All these factors can influence the degree of agreement between the informants and can be decisive for the clinician to take an informant or another more into account.
Nevertheless, this study has a number of limitations that should be considered. The sample has not been randomly selected; this study is not an experimental one, and the relationships between the variables could be affected by the effect of some uncontrolled variables. It is important to note that we have used two different self-report measures to compare the results of parents and children. We also note that EAT-40 evaluates the frequency of a behavior, while ABOS indicates the presence/absence of a behavior, which could bias the results. Likewise, self-reported measures have been used, so there is reliance on the sincerity of the participants in their answers. In addition, negation and minimization of the symptomatology are frequent in AN and this affects the psychometric results (Vitousek, Daly, & Heiser, 1991).
This study highlights the importance of conducting psychoeducational programs with parents on the symptoms of AN, in order to include them in the initial assessment of their adolescent children and in the diagnosis in the first phases of AN, because the more informed they are about the disease, the more reliable will be the diagnosis and prognosis established (Nicholls & Yi, 2012). In addition, the intervention of parents in the early stages of the disease will also be important. Mansson, Parling, and Swenne (2016) found that the parents’ ability to manage ED maintaining factors at the very start of treatment is a predictor for the short-term outcome in adolescents with restrictive symptoms. Among the implications for clinical practice applied to the study is the need to provide information, through media, health center, or school, regarding the first signals of alarm and symptomatology of AN, in order for parents to detect and take appropriate measures to avoid a chronic course of the disorder and receive adequate treatment for their children.
In conclusion, the evaluation of AN in adolescence is complicated, taking into account the tendency to minimize and deny the symptoms by adolescents and the difficulty of parents to detect the main symptoms. It seems that there are differences between parents in perceiving anorexic symptomatology of their children, wherein mothers detect better than fathers.
