The Pearson correlation coefficient results revealed a significant direct relationship between self-oriented and other-oriented perfectionism with suicidal ideation and a significant indirect relationship between the mentioned perfectionism components and suicidal ideation through mediating role of self-criticism. Moreover, a significant relationship was observed between self-criticism with perfectionism components and suicidal ideation separately.
Many empirical studies have supported the link between perfectionism and suicide (
37,
38). Tendency to perfectionism causes people to pursue maladaptive thoughts and behaviors. For example, all-or-nothing thinking in perfectionists causes them to see themselves as complete failures in all life stages, leading to suicidal ideation (
39). Empirical findings show that among perfectionism components, socially prescribed perfectionism is more associated with suicidal thoughts, perhaps because it leads to feelings of loneliness, isolation, and distress (
17,
40,
41). Regarding this form of perfectionism, people feel pressured by society's expectations they have no control over and cannot fulfill well; consequently, they are more likely to experience feelings of loneliness, isolation, and hopelessness (
42). It seems that socially prescribed perfectionists find themselves more pressured by people's expectations and opinions and are more likely than others to feel a lack of control over various aspects of their life. Therefore, they may consider suicide to escape from such societal pressures.
On the other side, findings show a significant relationship between self-criticism and suicidal thoughts. Researchers recognize the importance of the self-criticism variable in suicidal ideation (
43). Self-critical people view stressful situations as absolute failure due to over-criticizing, likely increasing the risk of suicide, as confirmed in similar studies (
44). Overly harsh self-criticism and self-evaluation can create feelings of guilt and worthlessness, providing ground for psychological impairments and distress.
In addition, studies show a significant relationship between perfectionism and self-criticism (
45), which is in line with the results of the present study. Rezaei and Jahan found that 33% of the self-criticism variable was determined by self-oriented and other-oriented perfectionism (
38). Self-oriented perfectionists seek very high standards and have unrealistic, unreasonable expectations of themselves, and since it is impossible to meet such standards and expectations, they criticize themselves. Other-oriented perfectionists also have unrealistic expectations from people, and as these high standards are not fulfilled, and they are not satisfied, they criticize themselves. By contrast, socially prescribed perfectionists direct their focus on others' standards and expectations and have no considerable personal criteria for evaluation; consequently, they are less self-critical or do self-criticism internally (
46).
Abnormal perfectionists' characteristics are as follows: Fear of making mistakes, excessive, unrealistic expectations from themselves and others, fear of failure, and being hesitant. These characteristics are essentially associated with psychological disorders, such as obsessive-compulsive disorders, depression, and anxiety (
47,
48). Perfectionists see their self-worth closely tied to their successes and achieving their goals. As perfectionists set high standards for themselves, they fail to achieve their goals and experience negative emotions (
49). As discussed previously, self-criticism is a mental impairment related to self- and other-oriented perfectionism (
23). It is associated with feelings of guilt, failure, worthlessness, and excessive self-blame, providing the basis for suicidal ideation. As a result, it can probably mediate the relationship between suicidal ideation and abnormal perfectionism.
Results of path analysis showed no significant relationship between other-oriented perfectionism and suicidal thoughts. Besides, the relationship was significant between self-oriented and socially prescribed perfectionism with suicidal ideation. These findings are consistent with the results of previous studies (
50,
51). Perhaps, as a result, other-oriented perfectionists strictly focus on people's shortcomings and weaknesses and attribute their problems and failures to others and sources outside of themselves (
23,
52,
53).
Characteristics of other-oriented perfectionists are as follows: Excessive expectations and demands from others, impatience, exploitation, and blaming others (
54). Self- and other-oriented perfectionism are related to self-relevant feelings of guilt and shame (
55,
56). Self-oriented perfectionists continuously set unrealistic, high standards for themselves and focus on their weaknesses and deficiencies (
57). Negative characteristics of self-oriented perfectionism include excessive self-criticism, precise and extreme programming, and over-responsibility leading to feelings of shame and guilt (
58). In truth, focusing on personal losses and feelings of shame and guilt causing self-blame may lead one toward suicidal thoughts to escape from inner tensions. Socially prescribed perfectionism, compared to other perfectionism components (i.e., self-oriented and other-oriented), is more related to fear of inferiority. Indeed, observation of others' inferiority or others' experience of inferiority causes the fear of inferiority. Also, fear of failure in such people is due to fear of being judged (
42,
56). Socially prescribed perfectionists are susceptible to interpret various situations in a way that leads them to feel the fear of inferiority; this can provoke a suicide crisis. Also, feeling a lack of control over behaviors and feeling trouble may lead to suicidal thoughts and behaviors (
59).
Using student sampling is one of the limitations of this study. The present study was conducted on students from the University of Science and Culture in Tehran. Thus, generalizing results should be done cautiously. Accordingly, it is suggested to conduct future research randomly on other populations with different demographic characteristics. In addition, data were collected using self-report tools that increase the likelihood of error in the interpretation of results and evaluation of research. Thus, it is better to use other data collecting tools in future research, such as clinical interviews. It is also suggested to identify students at suicide risk and hold planned training courses for them to prevent suicidal attempts by modify their perfectionistic characteristics and gain knowledge about ruminations and self-critical thoughts.
5.1. Conclusions
Perfectionism is observed to have a significant association with suicidal ideation with the mediation of self-criticism. In addition to the indirect effect of the self-criticism variable, this variable directly correlates with perfectionism and suicidal ideation. Among the three components of perfectionism, self-oriented and especially socially prescribed perfectionism have a significant relationship with suicidal ideation. Perfectionism and self-criticism can predict suicidal thoughts and behavior.
