Using the Clinical Management System CMS, patients with chronic medical disease will be identified and their appointment dates searched. On day of patient’s appointment, she/he will be screened on voluntary basis for depression, anxiety and stress using DASS-21 Chinese version. Patients screened to have negative emotional states with scores of Depression >4 and/or Anxiety>3 and/or Stress>7 will be invited to join this intervention. If patient agrees to join the study, informed consent will be signed. A convenient sampling of 30 eligible subjects will be recruited to account for 25% attrition rate. The 6-weekly 2-hr session group intervention will consist of 15 subjects. The other 15 subjects in the waiting list will be the control group.

Title: Impact of Positive Psychology Group Intervention for Chronic iIllness Patients with negative emotional states in Primary Care– A Prospective Experimental Study

Background: With the epidemic of non-communciable diseases, chronic illness such as heart disease, stroke, cancer, chronic respiratory diseases and diabetes, are by far the leading cause of mortality in the world . In Hong Kong, health care reforms have emphasized the importance of chronic disease management with multi-level, multi-disciplinary and multi-sectoral collaboration to achieve better health. There is also abundant evidence showing that patients with chronic medical illness represent a population at particularly high risk of mental disorders ranging from 20%-60%. The importance of promoting mental wellbeing while taking care of the medical needs of patients with chronic illness should be advocated. Different psychotherapeutic interventions including positive psychology has been shown to benefit patients with chronic disease. There is presently no published study on the effect of Positive Psychology Group Intervention for chronic illness patients with negative emotional states in primary care.

Aim: This study will introduce a multi-component Positive Psychology Group Intervention for chronic illness patients with negative emotional states and the aim is to provide preliminary evidence that Positive Psychology is an effective intervention modality..

Objective: This study attempts to assess whether Positive Psychology Group Intervention will be effective in reducing negative emotional states including depression, anxiety and/or stress, and enhance positive affect.

Eligible subjects will receive 6-weekly, 2 hrs per week of Positive Psychology Group Intervention consisting of 15 adults per group. The waiting list of 15 adults will be used as the control. This program will adopt multiple component interventions focusing on the several well-studied areas of positive psychology. It will include 6 multi-skills and techniques , some specific examples of skill techniques and weekly home assignments including Week 1and 2 :Noticing the positives, Optimism and gratitude journal, Week 3: Focusing on personal strengths, Week 4: Concept of Mindfulness and practice, Week 5: Hope and Teaching acts of kindness, Week 6: recapitulation and review.
