As a serious global public health issue, suicide is the fourth leading cause of mortality in 15–19-year-olds [1]. Suicide ideation is defined as thoughts about engaging in suicidal behavior, which confers risk for suicide attempts and completed suicide [2]. The rates of suicide ideation increase during early adolescence and reaching a peak at approximately the age of 15 years, then decline thereafter [3]. Besides contributing to mortality outcome, suicidal ideation in adolescence can produce negative consequences that last far into adulthood. Adolescents who reported suicidal ideation have a higher probability of psychiatric disorders, problem behaviors and compromised functioning [4, 5]. It is crucial, therefore, to better understand the factors that lead adolescents to consider suicide.
Harsh parenting typically involves parental discipline behaviors instance of yelling, spanking, slapping, shoving, or hitting the child with an object [6], which is characterized by a low acceptance and high strictness, and related to authoritarian style [7]. With verbally-abusive parenting (e.g., shouting, threatening, or yelling), and physically-abusive parenting (e.g., spanking) being the most universal forms [8], harsh parenting is highly prevalent around the world [9]. According to the interpersonal psychological theory of suicide, suicidal desire occurs when an individual experiences thwarted belongingness and perceived burdensomeness [10]. Adolescents who experiencing hash parenting may feel insecure in the family and develop the frustrated sense of belonging to family and see themselves as a burden or disappointment to other people, all of which can trigger suicidal ideation.
There is strong evidence that children exposed to harsh parenting are at risk for a myriad of adverse developmental outcomes such as anxiety, depression, negative self-evaluations, and internalizing problems behaviors [8,11,12,13,14]. Theses variables are in turn associated with suicide ideation [15], thus, harsh parenting may increase the odds of suicide ideation. Nevertheless, empirical connections between harsh parenting and suicide ideation are relatively rare. The present study aimed to examine the direct effect of harsh parenting on Chinese adolescents suicide ideation.
Despite harsh parenting may lead to suicide ideation directly, not all children who face such stressors will develop suicide ideation. As the stress-vulnerability model posits, suicidal ideation is determined not merely by the stressor but a multidimensional process that evolves through ongoing transactions of various variables such as personal traits and social support [16, 17]. The current study intends to analyse the association between harsh parenting and adolescent suicide ideation, with special attention to the roles of self-esteem and school support in this association, in order to provide effective suggestions for the prevention and intervention of adolescents suicide.
The Mediating Role Of Self-esteem
Self-esteem refers to an individual’s overall evaluation of self, is closely correlated with perceptions of others' evaluations of oneself [18, 19]. The sociometer theory proposes that self-esteem reflects a person’s relational value, which will increase when one being liked and accepted and decrease when one being rejected and excluded [19, 20]. As such, self-esteem is a construct saturated with both belongingness and burdensomeness and has been shown to be affected by parenting behavior [21, 22]. Negative feedback from significant others provides information that children many internalize, which lays the foundation for self-perceived incompetence and low self-worth [23]. Previous research has suggested that negative parenting practices may be detrimental to the self-esteem. For instance, one study by Smokowski et al. (2015) revealed that negative parenting strategies related to lower self-esteem [24]. Cole et al. (2016) demonstrated that harsh parenting predict the construction of depressive self-schemas in children and adolescents [11].
As an essential part of the individual’s self-concept, self-esteem is a protective factor linked to psychological functioning, which directly related to mental health during adolescence [25] and significantly predicted suicidal ideation [26]. For example, a cross-sectional study on teenagers in Vietnam discovered the connection between low self-esteem and suicidal ideation [27]. Similarly, a longitudinal study by Reid-Russell et al. (2021) suggested that implicit self-esteem is a potential mechanism linking childhood abuse to depression and suicidal ideation [28]. Based on the literature, it seems reasonable to infer that harsh parenting, as negative interactions between parents and children, may precede children’s low self-esteem, ultimately leading to suicide ideation.
The Moderating Role of School Social Support
School-aged youths spend more time in schools than in any other place except their homes. According to stage-environment fit theory, school is an essential developmental context for adolescents in which teachers and peers foster a environment that is responsive to the basic and developmental needs (e.g., interpersonal support) of adolescents [29, 30]. School provides a potential arena for adolescents to escape the negative parenting and fosters the sense of belonging and connectedness that may compensate for a lack of parental support. In addition, stress-buffering theory advocates that social support is a moderating factor in students’ lives, the perception of a strong social support could attenuate the adverse psychological effects of stressful events by strengthening internal resources for coping with negative life events [31].
Years of research have shown that the social support adolescents perceive from teachers and peers have a profound influence on mental health; it has been correlated negatively with depression, suicide ideation, and suicide attempts; and related positively with self-esteem, social skills and adaptive skills [32, 33, 34, 35]. For instance, the research conducted by Tang et al. (2018) found that peer acceptance lessened the deleterious effects of harsh parenting on adolescent depression through buffering the effect of negative self-cognition on depression [36]. Likewise, a recent study by Zhang et al. (2021) suggested that school belonging could moderate the direct relations between emotional abuse and suicide ideation [37]. Therefore, it is conceivable that school social support might compromise the negative impact of harsh parenting on adolescents self-esteem, also, school social support may abate the association between poor self-esteem and suicide ideation.
The Present Study
Aimed to further explore the relationship between harsh parenting and suicide ideation, the current study tested the mediation effects of self-esteem and the moderation effects of school social support involved in this relationship among adolescents in Chinese context. Based on the previous studies, three hypotheses are formulated: (1) harsh parenting may predict suicidal ideation;(2) self-esteem may mediate the association between harsh parenting and suicidal ideation; (3) school social support would moderate the relationship between harsh parenting and suicidal ideation via self-esteem.
