ItemEmotional self-awareness and depressive symptoms: an investigation of an early intervention mobile phone self-monitoring program for adolescents( 2012)Up to 30% of adolescents experience depressive symptoms before 18 years of age and are at risk of developing severe recurrent depression. There is, however, a lack of appropriate treatments available for these young people. Self-monitoring is often used in therapy to increase awareness about mood and distress, and is likely to decrease depressive symptoms. Furthermore, self-monitoring has potential as an early intervention tool for young people at risk of depression, particularly when mobile phones are used as a medium. Using both qualitative and quantitative methods, this thesis investigates the concept of emotional self-awareness (ESA) and its mediating role in the relationship between self-monitoring and depressive symptoms. To this end, several studies were conducted. First, a systematic literature review examining the benefits of ESA was conducted. A review of 50 publications found five common themes throughout the literature regarding ESA: (a) becoming aware of an emotional experience; (b) the ability to define and distinguish specific feelings; (c) identifying the contextual factors surrounding emotions; (d) communication of emotional knowledge; and (e) analysing emotional events to make decisions. Second, a post-hoc qualitative study examined secondary school students’ general feedback about ESA after self-monitoring. Spontaneous feedback from 20% of participants reported at least one ESA theme after completion of the self-monitoring program. Third, following from the post-hoc study, in-depth qualitative interviews were conducted with 37 young people after self-monitoring, specifically targeting ESA. This study provided rich descriptive detail about the themes of ESA from young people’s perspectives. Fourth, a preliminary measure of ESA was developed and tested with 22 young people with subclinical depressive symptoms, recruited from two general practitioners in a rural setting. This small-scale mixed-methods study combined an in-depth qualitative interview and a quantitative measure of ESA. Young people with high scores on the ESA measure had a different qualitative experience than those with low scores. Last, a randomised controlled trial examined the effects of self-monitoring on depressive symptoms when mediated by ESA. Young people with mild or more depressive symptoms were recruited from primary care settings and randomised into an intervention group (n = 68) or an attention-comparison group (n = 46). Mediation analysis demonstrated that self-monitoring significantly increased ESA in the intervention group when compared with the comparison group and that an increase in ESA significantly decreased depressive symptoms. Furthermore, there was a medium size of indirect effect (κ2 = 0.44) for depressive symptoms per week indirectly through ESA when compared with the comparison group. In summary, a useful model of ESA was developed in this thesis and tested across the studies suggesting that self-monitoring can increase ESA, which in turn, decreases depressive symptoms. Mobile phones are well suited to early intervention programs, providing an alternative to watchful waiting. Mobile phone self-monitoring programs should be considered as a first-step low-cost early intervention for young people who are at-risk of mental health problems. Self-monitoring has the advantages of helping young people increase their ESA while gaining more information about their mental health symptoms, which can also direct them to suitable interventions.
