Few studies have focused on exploring the association of self-efficacy and suicidal behaviour. In this study, we aim to investigate the association between health-related self-efficacy and suicidality outcomes, including lifetime/recent suicidal ideation, suicidal attempts and future intent of suicide.
A computer-assisted telephone interview (CATI) system was used to draw potential respondents aged over 15 in Taiwan via telephone numbers, which were selected by a stratified proportional randomization method according to the distribution of population size in different geographic areas of Taiwan. We obtained available information on suicide behaviours for the analysis of 2110 participants. Logistic regression was applied to investigate the independent effect of health-related self-efficacy on life-time suicidal thoughts and attempts.
Suicidality measured as suicide ideation and attempted suicide was reported as 12.6 and 2.7% respectively in the sample. Among those with suicide ideation, 9.8% had thoughts of future suicide intent. Female gender, low education, people living alone or separated, history of psychiatric disorders, substance abuse, poor self-rated mental health and physical health were associated with suicidality factors. Low health-related self-efficacy was associated with lifetime suicide ideation, prior suicide attempt and future suicidal intent. Among those with recent suicidal ideation, low health self-efficacy was independently associated with future suicide intent after adjustment of gender, age, education, marital status, substance abuse, psychological distress, poor mental and physical health.
Health-related self-efficacy was associated with suicide risks across different time points from prior ideation to future intention. Evaluation of the progress of self-efficacy in health may be long-term targets of intervention in suicide prevention strategies.
很少有研究关注自我效能感与自杀行为之间的关系。本研究旨在探讨健康相关自我效能感与自杀结果之间的关系，包括终身/近期自杀意念、自杀尝试和未来自杀意图。
通过电话号码，使用计算机辅助电话访谈 (CATI) 系统抽取年龄在 15 岁以上的潜在受访者，电话号码是根据台湾不同地理区域人口规模的分布情况，采用分层比例随机化方法选择的。我们获得了与自杀行为相关的可用信息，用于分析 2110 名参与者。应用 logistic 回归分析来探讨健康相关自我效能感对终身自杀意念和自杀尝试的独立影响。
在样本中，自杀行为表现为自杀意念和自杀尝试的比例分别为 12.6%和 2.7%。在有自杀意念的人群中，有 9.8%的人有未来自杀意图。女性、低教育程度、独居或分居、精神病史、物质滥用、自我评估的心理健康和身体健康状况较差与自杀因素有关。低健康相关自我效能感与终身自杀意念、既往自杀尝试和未来自杀意图有关。在近期有自杀意念的人群中，调整性别、年龄、教育程度、婚姻状况、物质滥用、心理困扰、心理健康和身体健康状况较差后，低健康自我效能感与未来自杀意图独立相关。
健康相关自我效能感与不同时间点的自杀风险相关，从既往意念到未来意图。评估健康自我效能的进展可能是预防自杀策略的长期干预目标。
