Mental health literacy in adolescents: ability to recognise problems, helpful interventions and outcomes

Abstract Background Although mental health literacy has been widely studied in adults, there are still relatively few studies on adolescent populations. In Sri Lanka, adolescents account for about one fifth of the population. Current evidence shows that most mental health problems diagnosed in adulthood begin in adolescence. There is also growing evidence that the trajectories of these disorders can be altered through early recognition and intervention. Although, help-seeking for mental health problems is known to be poor in adolescents, mental health literacy improves help-seeking. It is also known that adolescents may act as agents of change regarding mental health in their wider communities. Thus, mental health literacy in adolescents is an important aspect of community mental health initiatives. The objective of this study was to describe aspects of mental health literacy in terms of ability to recognise problems, helpful interventions, helpful referral options and outcomes in a target adolescent population in Sri Lanka. The association between socio economic variables and recognition of mental health problems was also examined. Methods This descriptive cross sectional study used a pretested questionnaire on 1002 adolescents aged between 13 and 16, where mental health literacy was assessed using 4 case vignettes. The vignettes represented depression with suicidal ideation, social phobia, psychosis and diabetes, where the last was for comparison. Results The response rates for recognition as a mental health problem was 82.2% (n = 824) for the vignette depicting depression, 68.7% (n = 689) for the psychosis vignette and 62.3% (n = 623) for the social phobia vignette. “Talking to the person”, was responded to as helpful by 49.9% (n = 500), for the depression vignette followed by 49.8% (n = 499) for social phobia, 39.5% (n = 396) for psychosis and 19.5% (n = 195) for the diabetes vignette. The response rate for exercise being a helpful intervention was 25% (n = 251) for the diabetes vignette, followed by 21% (n = 210) for social phobia, 18.7% (n = 187) for psychosis vignette and 18.4% (n = 184) for the depression vignette. While 70.2% (n = 704) responded that there would be benefit in seeing a doctor for the diabetes vignette, the response rates for psychosis was 48.5% (n = 486), and for both depression and social phobia it was 48.2% (n = 483). The responses for the persons in the vignettes becoming better with treatment was 81.4% (n = 816) for the diabetes, 79.5% (n = 797) for depression, 75.6% (n = 758) for psychosis and 63.4% (n = 636) for the social phobia vignette. A statistically significant association was found between the income level of the family and appropriate recognition as mental health problems, for all the 3 mental health related vignettes. Conclusions The ability to recognise mental health problems, helpful interventions and outcomes in this population was comparable to those of adolescent populations in other countries, with some exceptions. The main differences were in relation to the identification and interventions in response to the psychosis and social phobia vignettes
