Study Overview
Brief Summary
This study examined whether developing Psychological Capital (PsyCap) could help reduce suicidal thoughts among high school students in Guyana. Psychological Capital includes four positive psychological resources: hope, self-efficacy (confidence), resilience, and optimism.
High school students participated in a study that included a PsyCap development intervention. Students were assigned to either a treatment group that received the intervention or a control group. Psychological Capital and suicide ideation were measured before the intervention, immediately after the intervention, and at a one-month follow-up. The study examined whether students who received the PsyCap intervention experienced increased Psychological Capital and decreased suicide ideation compared with students in the control group.
The broader research also examined the relationship between Psychological Capital and suicide ideation using cross-sectional and longitudinal analyses and included interviews with individuals in Guyana who had previously attempted suicide.
Detailed Description
This study examined whether a Psychological Capital (PsyCap) development intervention could influence psychological capital and suicide ideation among high school students in Guyana. Psychological Capital is a positive psychological construct consisting of hope, efficacy, resilience, and optimism.
The quantitative component used a quasi-experimental, pre-post control group design. Participating high school students were assigned to treatment and control groups. The treatment group participated in a PsyCap development intervention designed to strengthen positive psychological resources through activities involving goal setting, identification of resources and obstacles, development of alternative pathways for achieving goals, and application of hope, efficacy, resilience, and optimism. Participants worked individually and in small groups during intervention activities. The facilitator connected the exercises to the psychological resources represented by PsyCap.
Psychological Capital and suicide ideation were assessed before the intervention, immediately following the intervention, and at a one-month follow-up. These repeated assessments were used to examine changes over time and differences between the treatment and control groups. The study also examined the relationship between PsyCap and suicide ideation using cross-sectional and longitudinal analyses.
The study was designed to test whether higher levels of Psychological Capital were associated with lower levels of suicide ideation and whether development of Psychological Capital could lead to a decrease in suicide ideation. Counseling professionals and school guidance personnel were available to provide support in connection with study participation.

Masking Description
The lead investigator was masked to participant group assignment prior to the intervention. Masking ended when the intervention was initiated because the investigator delivered the intervention.

Arms & Interventions
Psychological Capital (PsyCap) Intervention
Participants assigned to the intervention arm received a Psychological Capital (PsyCap) development intervention designed to strengthen hope, efficacy (self-confidence), resilience, and optimism. Intervention activities included identifying meaningful goals, developing sub-goals, identifying available resources and potential obstacles, and generating multiple pathways for overcoming obstacles and achieving goals. Participants also engaged in small-group activities to share plans, ideas, and possible solutions. The facilitator connected the exercises to the PsyCap components throughout the intervention.
Intervention: Psychological Capital (PsyCap) Development Intervention (Behavioral)
Control
Participants assigned to the control arm did not receive the Psychological Capital (PsyCap) development intervention during the study period and served as the comparison group. Participants completed the same study assessments used to measure Psychological Capital and suicide ideation at the designated assessment time points.
Outcomes
Primary Outcomes
Change in Lifetime Suicide Ideation
Time Frame: Pre-intervention, immediately post-intervention, and 1-month follow-up
Lifetime suicide ideation was assessed using participant survey responses. Lifetime suicide ideation was assessed using the suicide ideation subscale of the Columbia-Suicide Severity Rating Scale (C-SSRS), as modified by Núñez et al. (2019). The measure consisted of six progressive Yes/No items assessing lifetime suicide ideation. Responses were used to derive a score ranging from 0 to 6. The minimum score was 0 and the maximum score was 6. Higher scores indicated greater severity of suicide ideation and therefore a worse outcome; lower scores indicated less suicide ideation and therefore a better outcome. Scores were compared between the Psychological Capital (PsyCap) intervention and control groups across assessment time points.
Change in Last Month Suicide Ideation
Time Frame: Pre-intervention, immediately post-intervention, and 1-month follow-up
Last Month Suicide Ideation was assessed using the suicide ideation subscale of the Columbia-Suicide Severity Rating Scale (C-SSRS), as modified by Núñez et al. (2019). The measure consisted of six progressive Yes/No items assessing suicide ideation during the previous month. Responses were used to derive a score ranging from 0 to 6. The minimum score was 0 and the maximum score was 6. Higher scores indicated greater severity of suicide ideation and therefore a worse outcome; lower scores indicated less suicide ideation and therefore a better outcome. Scores were compared between the Psychological Capital (PsyCap) intervention and control groups across assessment time points.
