Show moreBackground: Suicidality could be associated with specific combinations of biological, social and psychologicalfactors. Therefore, depressive episodes with suicidal ideation could be different from depressive episodeswithout suicidal ideation in terms of latent variable structures.Methods: In this study we compared latent variable structures between suicidal and non-suicidal depressedpatients using confirmatory factor analysis (CFA), following a measurement invariance test procedure. Patients(N = 919) suffering from major depressive disorder were selected from the Netherlands Study of Depression andAnxiety (NESDA) and split into a group that showed no symptoms of suicidal ideation (non-SI; N = 691) and asuicidal ideation (SI) group that had one or more symptoms of suicidal ideation (N = 228). Depression andanxiety symptoms were measured using the short form of the Mood and Anxiety Symptoms Questionnaire(MASQ-D30).Results: CFA implied a difference in latent variable structures between the non-SI sample (CFI 0.957; RMSEA0.041) and the SI sample (CFI 0.900; RMSEA 0.056). Subsequent multiple-group CFA showed violations ofmeasurement invariance. The General distress and Anhedonic depression subscales were best indicated byhopelessness and lack of optimism in the SI sample and by dissatisfaction and not feeling lively in the non-SIsample. Overall, the SI sample had higher scores and lower inter-item correlations on the Anhedonic depressionitems.Limitations: We have included very mild cases of suicidal ideation in our SI sample.Conclusions: On a latent variable level, depression with suicidal ideation differs from depression without suicidalideation.

Show morePrevious studies reveal an elevated suicide rate for anaesthesiologists. We sought to examine anaesthesiologist suicide mortality and its underlying explanatory factors. Two studies were conducted in order to establish the suicide mortality figures among Dutch anaesthesiologists and to investigate life events, workrelated stress, psychological problems and alcohol- and drug abuse in relation to suicidal ideation. The results suggest that suicide mortality in anaesthesiologists in The Netherlands is elevated, and comparable to that in other Western countries, but small numbers prevent robust testing of this difference. Anaesthesiologists are more likely than the general population to experience sleeping problems and suicidal ideation; male anaesthesiologists are more likely to suffer from depression. The prevalence of suicide among this population may be related to a high prevalence of psychological problems, in addition to the knowledge and availability of means. Areas of suicide prevention among this group are discussed. Show less

Show moreDysfunctional self-schemas are assumed to play an important role in suicidal ideation. According to recent information-processing models, it is important to differentiate between 'explicit' beliefs and automatic associations. Explicit beliefs stem from the weighting of propositions and their corresponding 'truth' values, while automatic associations reflect more simple associations in memory. Both types of associations are assumed to have different functional properties and both may be involved in suicidal ideation. Thus far, studies into self-schemas and suicidal ideation focused on the more explicit, consciously accessible traces of self-schemas and predominantly relied on self-report questionnaires or interviews. To complement these 'explicit' findings and more directly tap into self-schemas, this study investigated automatic self-associations in a large scale community sample that was part of the Netherlands Study of Depression and Anxiety (NESDA). The results showed that automatic self-associations of depression and anxiety were indeed significantly related to suicidal ideation and past suicide attempt. Moreover, the interactions between automatic self-depressive (anxious) associations and explicit self-depressive (anxious) beliefs explained additional variance over and above explicit self-beliefs. Together these results provide an initial insight into one explanation of why suicidal patients might report difficulties in preventing and managing suicidal thoughts. Show less
