A Qualitative Study Exploring International Experiences of Seeking Treatment for Adults With Trichotillomania: A Story of Frustration and Unmet Need

Introduction

Trichotillomania (TTM) is a poorly understood disorder (1) commonly resulting in clinically significant distress and impairment across all aspects of life, with subsequent hair loss not attributable to another medical condition or mental health disorder (2). Secrecy and non-disclosure tendencies of people with TTM and lack of awareness by healthcare professionals (3) all contribute towards diagnostic under-recognition in the general population. Prevalence was largely unknown for decades; the first large epidemiological survey examining prevalence in a USA general population sample (4) revealed 1.7% of participants as having current TTM, with the lifetime TTM rate at 2.5%. There is a dearth of qualitative enquiry around TTM with cross-cultural research being limited (5).

TTM impacts health and wellbeing in numerous ways; physical complications including skin infections, bleeding, irritation and inflammation from excessive hair-pulling (3). Trichophagia (ingesting hair) is associated with risk of trichobezoar (mass of ingested hair) which can prove fatal without surgical intervention. Functional outcomes associated with TTM include impairment in social, occupational, academic and psychological functioning (1). Chronic hair-pullers often experience depression, anxiety, embarrassment, feelings of unattractiveness and low self-esteem (6). TTM is known to be a distressing disorder commonly linked to secrecy and shame; a lack of understanding about the availability and efficacy of interventions further contributes toward poor prognosis and routine outcomes (7). Little is known about the experience of people living with TTM from a qualitative perspective and despite several reviews (3,7), little is known about the cause, epidemiology or aetiology of TTM, with treatment yielding mixed results at best (3). This article reports participant access to and experiences of seeking treatment for TTM.

Method

A generic qualitative approach was utilised (8). Data originated from an international sample and comprised in-depth asynchronous email interviews. Ethical approval was granted by a university research ethics panel. Participants provided informed consent, were notified of their rights to anonymity, confidentiality and rights of withdrawal from the study. Participants were debriefed and provided with support measures at the end of participation. A purposive sampling strategy was utilised to specifically recruit individuals with a common experience of having TTM. Semi-structured asynchronous email interviews (9) were flexible and took place over 8–10 email exchanges. Inclusion criteria contained screening questions guided by the DSM-5 criteria for TTM (2). Exclusion criteria included a screening question which aimed to identify anyone who considered themself to be at risk. Within the international sample, the ability to speak and write in English was not a pre-defined criterion; the general message seeking participants was written in English and only participants who could respond in English volunteered their participation. Data were analysed using the six-phase thematic analysis process by Braun and Clarke (10); a method that is largely independent of theory and offers a flexible process of analysing data. The thematic analysis was developed inductively to locate semantic level themes, aiming to facilitate data driven findings. Nested within a larger study, participants were asked questions related to their experiences of seeking treatment for TTM.

Results

During 2016, email interviews were conducted with 20 participants (13 female) from 15 countries; mean age 34.3 years; age range 18–55 years; reported onset of TTM range was 5–26 years; TTM had been experienced for an average of 20.05 years. Sample demographics are noted in Table 1. Four people dropped out of the interview citing various reasons (e.g. change of mind, time constraints) and six people began the interview but stopped responding; dropout and non-responder data were not used. Thematic analysis highlighted one theme; lapse in duty of care, and one sub-theme; inadequate training of healthcare professionals.

Discussion

TTM impairment appears to worsen over time; mild to moderate social and interpersonal impairment is evident in childhood (11) which often progresses to moderate to severe impairment in later life (1). Participants’ accounts of their unmet healthcare needs suggest early intervention may impact positively on health and social outcomes. Often the first point of contact, GP's face a formidable challenge when dealing with patients who have complex symptoms (12) of disorders with no known aetiology. People with TTM may benefit from improved access to psychological therapies, especially those with chronic symptoms as they often experience comorbidity and make heavy demand on multiple healthcare services, with generally unsatisfactory outcomes (13). TTM symptoms may often exacerbate comorbid disorders and vice versa; there is a tendency within specialist services to keep things separated, this can result in people with comorbidity falling through the cracks (14) and signals a need for partnership across healthcare departments.

Treatment seeking behaviours are low within the TTM population; in one study, just over 61% of survey participants sought treatment, but only 14.8% reported a moderate to large reduction in TTM symptoms (1). Current findings suggest treatment seeking commonly results in unmet healthcare needs; this finding can be used to inform how clinicians better understand and support people with TTM. Previous research (3,15) highlighted an inadequate supply of healthcare providers trained to treat TTM and called for more information and training to address the global shortage of therapist expertise. Unfortunately, based on the current findings, this has remained the same a decade later. Participant accounts of perceived repulsion on the part of the clinicians suggests professional support could in some cases be adversely influenced by clinicians’ personal feelings about TTM; relevant training for clinicians could therefore include an examination of conscious and unconscious bias. To compare current findings, future research may investigate healthcare professional perceptions and experiences of supporting patients with TTM. Previous research noted low clinician ratings of impairment for TTM patients (16); this contradicts accumulating evidence which highlights the negative consequences associated with TTM and further emphasises that TTM is a misunderstood disorder.

As comorbidity is common with TTM, clinical services should aim to utilise an inclusive approach whereby provisions should be needs-led rather than service-led (14). Arguably, study findings emphasise the importance of patient-centred support that offers an appropriate response to people with TTM experiencing distress. Further, coupled with the need for TTM training in the healthcare field, there should be a move toward development and pilot of a novel, accessible specialist service for people with TTM. The asynchronous email interview method provided an acceptable and feasible way to access an international sample of people with TTM, while eliminating the need to travel. Long-term email engagement facilitated rapport. The method was effective in highlighting participants’ shared experience of misunderstandings on the part of clinicians, delayed diagnosis and difficulty accessing appropriate TTM treatment.

Limitations

Interviews that take longer to complete may result in a higher possibility of dropouts (17). Given the sample size; it was not a specific aim to produce generalisable findings. Despite reported limitations of internet recruitment, internet sampling procedures can provide results consistent with traditional methods (18). Limited clinical and demographic information was gathered, though the inclusion of screening questions guided by the DSM-5 criteria for TTM () (2) may have mitigated the absence of verified participant diagnoses.

Conclusion

TTM remains a misunderstood disorder with poor prognosis. The wide-ranging impairments and comorbidities associated with TTM imply high societal costs, highlighting a need for greater knowledge and understanding of the condition. Many people with TTM are underserved and have unmet healthcare needs; guidance for practitioners on this subject is generally sparse, changes to policy and practice are warranted and provision of education for clinicians is needed. These findings can inform how clinicians support people with TTM and suggest avenues for further research.
