Testing the relationship between a self-management intervention for recurrent depression and health outcomes.

BACKGROUND: Depression is a leading cause of disability globally. It is a recurrent chronic illness that affects over three million people worldwide. Self-management has been found to positively impact depression outcomes but few techniques or interventions are theory-based and can be used either with or without the support of mental health care providers.

OBJECTIVES: This study aimed to test the relationship between a self-management intervention called the Self-Regulated Illness Management of Depression (SRIM-D) intervention and specific health outcomes (depression, self-efficacy, social support and quality of life). SRIM-D was developed using metacognition and self-regulation theories.

SAMPLE AND SETTING: Twenty-three individuals with major depressive disorder (MDD) participated in the study. Individuals over 21 years of age without a diagnosis of bipolar disorder, current substance abuse problem or suicidal ideations who suffered from MDD (BDI-II < 19) were considered for the study.

METHODS: The intervention was delivered over three consecutive weeks of 1 ½ hour sessions by two PhD prepared nurses with psychiatric experience. Participants were given a workbook manual with corresponding power point presentations conferring information about depression, and were led through a series of workbook activities designed to teach the self-regulation process as applied to their recurrent depression. Health outcomes were assessed via self-report survey prior to and six-month post-intervention.

RESULTS: Six months post-intervention depressive symptoms decreased significantly (M = 6.62, SD = 14.76, t(15) = 5.60, p < .0001). Self-efficacy (M = 161.67, SD = 25.27); t(20) = -2.89, p < .01) and quality of life (13.25, SD = 3.61; t(19) = 2.62, p > .01) both improved significantly. Social support had a negligible, insignificant decrease from pre-intervention (M = 53.05, SD = 19.81) to six months post-intervention (M = 42.14, SD = 19.53).

CONCLUSIONS: Overall, the SRIM-D intervention improved health outcomes in this study. The intervention demonstrated applicability to people with recurrent, chronic depression who might or might not have access to care.
