Suicide is a public, serious, and preventable health problem. Suicide behavior is a range of suicide ideation, suicide attempts, and full suicide. Suicide ideation is defined as the thoughts that are related to the personal cause of the individual death (
1) and include suicidal thoughts or suicide threats without any action. The prevalence of suicide ideation has been reported in a range of 2% - 18% (
2). The prevalence of suicide in university students is such that, between 2000 and 2002, 4,390 committed suicide in US (
3).
Previous studies concentrated on the risk factors of suicide. According to research evidence, the rate of suicide among single, young people is more common (
3). Low self-esteem (
4), poor problem-solving capabilities (
5), frustration, depression (
6), dissatisfaction, pessimism, anxiety and anxiety disorders (
7), drug abuse disorders (
8), negative life events (
9), family problems (
10) and economical problems (
3) have all been related to suicide ideation. Personality traits have been the important factors in predicting suicide ideation: neuroticism, introspection, anxiety, aggression, impulsivity, suspicion, despair, self-criticism, perfectionism, feeling of guilt, anger, and irritability are risk factors. Tolerance, endurance, complacency, and self-esteem stability are the protective factors against suicide (
11).
Recently, self-compassion has been considered to be a crucial predictor of mental health (
12). Self-compassion is a normal form of self-acceptance that represents the acceptance level of undesirable aspects of ourselves and our lives. This structure includes three main components: self-kindness and self-understanding in times of suffering or perceived inadequacy; common humanity and identifying that pain and frustration are the inevitable aspects of the common human experience; and balanced awareness of personal emotions, defined as the ability to encounter (not avoid) without any exaggeration, showing self-pity without painful thoughts and emotions (
12). It has been shown that increasing self-compassion predicts cognitive mental health over time (
13). Neff et al. (
14) found that self-compassion is associated with intrinsic interest in learning and normal coping strategies after failing in a test. Basharpoor and Isazadegan (
15) show that self-compassion is negatively correlated with depression. Akin et al. (
16) showed that. although self-compassion plays an important role in self-confidence, it is not related to narcissicm.
Some theories consider suicide ideation as the climax of negative emotions, especially anger toward the self. Anger is a multidimensional emotion and physiological experience that is expressed in internal and external forms, either of which could independently affect the individual psychosocial functions. Anger-in is the feature of the behavioral inhibition system and is defined as the tendency toward thought suppression and hostile behaviors aimed at the ego and self and is shown as negative emotions such as depression and guilt (
17). Anger-out is related to the behavioral activation system, and it is often expressed as direct or indirect physical or verbal aggressive behaviors toward people or objects in the environment (
18). Theoretically, there is a relationship between anger and suicidal behavior. Some evolutionary and psychodynamic theories express that anger and suicide are related conceptually in that both of them have an adaptive and unloading goal and are rooted in aggression (
19). People with problems related to anger indicate a range of cognitive and interpersonal deficits with deleterious effects on mental health that play a role in the increased risk of suicide behaviors (
20).
Considering the high prevalence of suicide ideation and the importance of identifying its related factors, this study aimed to determine the relationship of self-compassion and anger control dimensions with suicide ideation in university students.
