This study sought to analyze the structural relationships between optimism, distress tolerance, grief avoidance, intrusive rumination, deliberate rumination, and psychological well-being among undergraduates who have experienced a loss.

Subjects comprised 435 university students (258 females and 177 males), with their duration of grief experience and the elapsed period from when the loss occurred having been taken into consideration.

Distress tolerance, grief avoidance, intrusive rumination, and deliberate rumination mediated the relationship between optimism and psychological well-being sequentially. Additionally, there were significant differences between the “less than 6 months” and “more than 6 months” groups in the structural relationships between optimism, distress tolerance, grief avoidance, intrusive rumination, deliberate rumination, and psychological well-being.

The direct path of grief avoidance to psychological well-being was not significant, but it was found to have a significant effect through the sequential mediations of intrusive rumination and deliberate rumination. This result suggests the need for active intervention to allow people to face and cope with life after a loss, without avoiding the loss experience.

The purpose of this study, which uses an nonequivalent control group non-synchronized design, was to develop of a self-empowerment intervention program for for inpatient at high risk of suicide, and to assess its effects on positive emotions (subjective well–being, psychological well–being, gratitude, optimism, Self-esteem), empowerment and suicide ideation.

Data were collected from January to December, 2016. The experimental group participated in 8 sessions of self-empowerment intervention program. The control group was granted general intervention program to the psychiatric ward. The collected data were analyzed in SPSS Win 20.0.

The results of this study showed the proposed self-empowerment intervention program for inpatient at high risk of suicide had the effect of improving positive emotions (subjective well–being, psychological well–being, gratitude, and optimism, self-esteem), empowerment and reducing the suicide ideation.

The program, developed in accordance with King’s theory of goal attainment, will serve as a useful reference in developing standard guidelines for nursing intervention program suicide prevention in psychiatric department. The results are expected to contribute to the practice of intensive nursing care for inpatient at high risk of suicide.

This study examined the effect of optimism intervention consisting of writing and mental imagery about best possible self (BPS) and implementation intention on depression, optimism, subjective well-being, self-efficacy in college students.

Sixty depressive college students were randomly assigned to BPS condition (n=21), BPS & implementation intention condition (n=20), and control condition (n=19). Depression, optimism, emotional well-being, cognitive well-being, self-efficacy were measured before and after each intervention. The pre-and post-survey data were analyzed through ANCOVA.

The results showed that compared to the control intervention, BPS intervention led to significantly larger decrease in depression and significantly larger increase in optimism, emotional well-being, cognitive well-being, and self-efficacy. Compared to the control intervention, BPS & implementation intention intervention led to significantly larger decrease in depression and significantly larger increase in optimism and emotional well-being.

These findings suggest that optimism intervention and implementation intention has therapeutic implication in depressed group. Finally, the clinical implications and limitation of the present study were discussed.
