The Effectiveness of Psychological Well-being Training on Optimism and Self-care Behaviors in Adolescents with Type 1 Diabetes

 Today, health psychologists seek to improve the performance of patients with type 1 diabetes and increase their well-being through increasing their adherence to self-care behavior. The purpose of this study was to determine the effectiveness of psychological well-being on optimism and self-care behaviors in patients with type 1 diabetes.

 The current study was a quasi-experimental study with a pretest-posttest design and a control group. The statistical population included all adolescents with type 1 diabetes who were members of the Bandar Abbas Diabetes Association in 2022. Through purposeful sampling, ‎30 adolescents with type 1 diabetes were selected and randomly (odd and even numbers) divided into intervention (15 participants) and control groups (15 participants). Psychological well-being education was presented to the experimental group in 10 weekly 90-minute group sessions. In contrast, the control group did not receive any interventions. The research tools include the Revised Life Orientation Test (LOT-R) (Shier & Carver, 1985) and Revised Diabetes Self-Management Questionnaire ‎‎(DSMQ-R)‎ (Tolbert et al., 2000). Multivariate analysis of covariance (MANCOVA) was used in the current study (P < 0.05). All statistical analyses were performed in SPSS software.

 The findings of this study showed that psychological well-being training significantly increased optimism (F = 25.43; P < 0.001) and self-care behaviors (F = 29.76; P < 0.001).

 It can be concluded that psychological well-being intervention was beneficial for patients with type 1 diabetes and it showed promising effects on clinically relevant outcomes.
