War captivity is one of the most severe human-inflicted traumatic experiences with wide and substantial long-term negative effects. However, only one retrospective study examined suicidal ideation (SI) among ex-prisoners of war (ex-POWs). This study aimed to prospectively assess SI among ex-POWs and its associations with posttraumatic stress disorder (PTSD) symptoms over a 17-year period. Two groups of male Israeli veterans from the 1973 Yom Kippur War were examined: ex-POWs and comparable veterans who were not taken captive. Both groups were assessed via self-report measures of SI and PTSD symptoms at three time points: T1 18 (1991), T2 30 (2003), and T3 35 (2008) years after the war. Latent growth curve modeling (LGM) results showed that ex-POWs reported higher levels of SI at T2 and T3 and a pattern of increase in SI levels trajectory over time, compared to control veterans. Furthermore, among ex-POWs, PTSD symptoms at T1 contributed to the increase in rate of change in SI overtime. In addition, PTSD symptoms affected SI at the same measurement, above and beyond above the trajectories of SI. Clinical implications of these findings for the relations between captivity trauma and suicidality are discussed.
战俘经历是人类遭受的最严重的创伤性经历之一，会产生广泛而实质性的长期负面影响。然而，仅有一项回顾性研究调查了战争退役军人（ex-POWs）中的自杀意念（SI）。本研究旨在前瞻性评估 17 年内 ex-POWs 中的 SI 及其与创伤后应激障碍（PTSD）症状之间的关联。研究对 1973 年赎罪日战争中的两组以色列男性退伍军人进行了检查：战俘和未被俘的可比退伍军人。两组均通过 SI 和 PTSD 症状的自我报告评估在三个时间点进行评估：T1 18 （1991 年），T2 30 （2003 年）和 T3 35 （2008 年）。潜在增长曲线模型（LGM）结果表明，与对照组退伍军人相比，战俘在 T2 和 T3 报告的 SI 水平更高，且 SI 水平轨迹随时间呈上升趋势。此外，在战俘中，T1 时的 PTSD 症状导致 SI 随时间变化的变化率增加。此外，PTSD 症状在相同的测量时间上影响 SI，超过了 SI 轨迹。讨论了这些发现对被俘创伤与自杀之间关系的临床意义。
