1. Introduction

Parenting is the general child-rearing practice in day-to-day life. Parenting practices have both long- and short-term impacts on the development of the children affecting the psychical, emotional, and mental health [1]. It plays important role in developing and perpetuating childhood psychiatric disorders. Parenting style characterizes the child-rearing practice in several categorical aspects to measure [1, 2]. Baumrind classified the parenting styles into three types mentioned as authoritative, authoritarian, and permissive based on two dimensions, i.e., demandingness and responsiveness [3]. Maccoby and Martin added an additional type of parenting to the existing threes creating four types of parenting, i.e., authoritative, authoritarian, permissive, and neglectful [4]. The authoritative parents have a balance between the demandingness and responsiveness with children; the authoritarian parents have high demandingness and low responsiveness; the permission parents have low demandingness and high responsiveness; the neglectful parents have no definitive pattern, usually have low demandingness and low responsiveness [37]. However, the type, dimensions, and impact of parenting are subjected to vary from culture to culture [1, 2]. Among the types of parenting, authoritative parenting has been found to be associated with positive outcomes than other types which are replicated in western countries. Children with authoritative parents are more like to have higher perceived well-being, self-esteem, and life satisfaction, and most appropriate long-term development [1]. They also have higher academic achievements, problem-solving strategies, and a lower rate of internalizing and externalizing problems, and substance abuse [1]. Parental harshness (rejection and physical punishment) is associated with anxiety, depression, social anxiety somatic symptoms, aggressive behavior, bullying, and suicidal behavior [1, 8]. Parental responsiveness is associated with a lower rate of depressive disorder, eating, social anxiety, and substance abuse [1]. There is a dearth of empirical studies assessing the types, dimensions, and impact of parenting on the short- and long-term development of the children, especially in non-western and Low-and Middle-Income Countries (LMICs).

Suicide is a global public health problem affecting more than 700,000 people in 2019 in the world [9]. It is the fourth leading cause of death among 15-19-year old [9]. Suicide is an extremely complicated phenomenon with multifaceted interactions among risk factors in different aspects like stress-diathesis interaction, gene-environment interface, proximal, and distal risk factors connections [10, 11]. Hawton and van Heeringen identified several distal risk factors for suicide mentioned as genetic loading, personality traits with impulsivity and aggression, less fetal growth and perinatal complications, early adverse life events, and neurobiological problems [12]. The paper also mentioned some proximal risk factors like mental illness, physical diseases, psychosocial crisis, availability of methods, and being exposed to models [12].

Replicating empirical studies assessed the influence of parent-child relationship on suicidal behavior and revealed that there should have been an undeniable relationship especially when a family endures a disrupted environment prevailing parental discord, parental separation, frequent change in caregiver, and physical or sexual abuse [13]. However, there is a lack of efforts to synthesis the reviews from the empirical studies assessing the impact of any individual parenting style and suicidality (thought/idea, plan, and attempt). On this background, we aimed to see the relationship between parenting style and suicidal behaviors across the life span from available empirical studies. In the current review, we considered suicidal behavior that suicidal idea/thought, plan, and attempt.

2. Methods

2.1. Search Strategy

A search was conducted in Medline, Embase, and PsychINFO to identify the articles assessing the relationship between different types of parenting styles and suicidal behavior. We included the articles published from inception to search date. The search details are mentioned in supplementary file 1. Stepwise article selection is mentioned in Figure 1.

2.2. Inclusion Criteria

Original articles, studies with quantitative estimates, published in the English language, and articles available in full-text were included.

2.3. Exclusion Criteria

Qualitative studies, studies published in other language, other type of studies, i.e., review, editorial, erratum, and letters were excluded.

2.4. Data Extraction

We scrutinized 32 articles from different countries of all the continents of the world. We identified the studies, publication year, country of the study, instruments used to measure the parenting style and suicidality, sample size, study population, study design, data collection technique, and summary highlighting the relationship between parenting style and suicidal behavior. The extracted variables are mentioned in Table 1.

2.5. Ethical Aspects

We reviewed secondary publicly available articles. Therefore, no institutional review board approval was sought to conduct the study.

3. Results

3.1. Distribution of the Studies

The review included 32 original studies from different countries of all the continents of the world (Figure 1). Among the included studies, 27 studies used a cross-sectional study design, three studies used longitudinal follow up design, and the remaining two studies were retrospective cohort studies. Only three studies are published before 2000, six studies are published between 2000 and 2010, a vast majority (17) studies were published between 2011 and 2020, and only two studies were published in the year 2021 (Table 1).

3.2. Distribution of Population

Almost every single study used a sample size of more than 100 with one exception; the study published in Australia in 1987 used 43 cases and 42 controls. In most of the studies, the age of the study population varied from 9 to 21 years (Table 1). The majority of the population was taken from nonclinical apparently health groups (68.57%; ). However, the population was undergraduate medical students in four studies, and hospitalized patients in two studies. Sixteen studies used self-reporting measures for data collection, eight studies used the interview method, survey methods were used by six studies, and a single study used cohort design.

3.3. Distribution of the Instruments
3.3.1. Instruments Measuring Parenting Style

There is not very much similarity when it comes to using research instruments among the included studies. A total of eight studies have used Parental Bonding Instrument (PBI), three studies used Child Behavior Checklist (CBCL), two studies used Parental Authority Questionnaire (PAQ), and remaining studies used Parent-Child Conflict Tactics Scale (PCCTS), Childhood Experience of Care and Abuse (CECA), Measure of Parental Style (MOPS), Short Egan Minnen Barndoms Uppfostran Chinese Version (S-EMBU-C) for parenting style, Perception of Parenting Style and Practices (PPSP), Warmth and Acceptance Scale (WAS), Gratitude Questionnaire (GQ-6), and Influential Relationships Questionnaire (IQR) (Table 1).

3.3.2. Instruments Measuring Suicidal Behavior

The studies used various instruments to measure suicidal behavior such as Self-Injurious Thoughts and Behavior Interview (SITBI), Health Behavior in School-aged Children (HBSC), Massachusetts Youth Screening Instrument (MYSI), Adolescent Suicide Questionnaire (ASQ), Childhood Experience of Care and Abuse (CECA), Suicidality subscale of the Korean Version of the Composite International Diagnostic Interview (K-CIDI version 2.1), Risk for Suicide Questionnaire (RSQ), Scale for Suicidal Ideation (SSI), and General Health Questionnaire (GHQ-28) (Table 1).

3.4. Association of Parenting Style and Suicidal Behavior

This review has identified that there are several parenting factors, which are responsible for suicidal behavior among children and adolescents. Eight studies revealed that authoritarian parenting style is one of the predictors of suicidal behavior among the participants, and one study reported that authoritarian parenting style was found to be a resilient factor. Dominating and flexible parenting styles were also associated with higher suicidal behavior according to two different studies, and two studies reported that permissive style of parenting is also a contributing factor for suicidal ideation among participants. Other significant factors reported by other studies are paternal criticism, less caring and overprotective nature of parents, parental neglect, lack of adequate supervision single mother upbringing, less maternal affection, overprotectiveness, the curvilinear relationship between parental involvement, maternal overcontrol, low paternal warmth, and negative child-rearing practices, physical punishment from the parents, indirect association between childhood maltreatment, demanding parenting, and abuse from parents.

4. Discussion

The aim of the present review was to examine the empirical evidence for an association between parenting styles and suicidal behavior (thought/idea, plan, and attempt) across age groups. Our search efforts revealed a considerable increase in research focus on parenting and suicidal behavior with time; more than half of the reviewed studies were published in the last decade (2011-2020). We found that the parenting style most associated with increased suicidal behavior across the reviewed studies was authoritarian parenting. However, discordant findings were also noted. Relatively, limited evidence also points to the role of dominating, flexible, and permissive parenting in fostering suicidal behavior. Other key parenting factors that have been shown to increase the risk of suicidal behavior include inconsistent parenting style, parental neglect, being raised by a single mother, and overprotective parenting. Interestingly, one study showed a curvilinear relationship between parental involvement and suicidal behavior; while greater parental involvement decreased suicidal behavior to some extent, after a certain level, the relationship reversed. Parental involvement, in this context, refers to levels of parental monitoring and regulation of child’s behavior. These results imply that whereas an optimal amount of parental support and involvement may serve to buffer stress, too much of it may undermine autonomy and self-efficacy, threatening psychological health and outcomes.

Globally, suicide is a leading cause of death among adolescents and young adults aged between 15 and 29 years [9]. Recent reviews that focused on developments in epidemiology and risk factors for youth suicide have consistently highlighted the etiological role of family factors such as quality of the parent-child bonding, childhood maltreatment, family strife, and parental psychopathology in adolescent suicidal behavior [14]. Findings from the Global School-based Health Survey (GSHS) that explored the association between parent-child relationship and adolescent suicidality in more than 50 countries worldwide also concluded similarly; an adolescent’s positive perceptions about parenting had a protective effect on suicidal behavior [15]. Further, the authors also found some evidence for gendered effects in this relationship; the protective effects of parent-child relationship on suicidality were marginally stronger among girls than boys. Interestingly, in low-income countries, compared to middle- and high-income countries, the quality of parenting exerted lesser effects on adolescent suicidal behavior. Evidence suggests that authoritarian and rejecting-neglecting parenting styles are associated with an increased risk of suicidal behavior [16].

The stress-diathesis model of suicide provides a theoretical basis for understanding both the positive and negative influence of parenting on youth suicidal behavior. Simply put, this model conceptualizes suicidal behavior as emerging from an interaction between the individual vulnerability, or diathesis, and exposure to stressors, such as stressful life events or psychiatric morbidity [17]. Early childhood experiences, that are linked to parenting, such as low levels of parental warmth, rejection, and inconsistent parenting are tied to insecure attachment and negative emotions in children, both of which have been identified as risk factors for subsequent suicidal behavior [18]. In individuals with such a preexisting diathesis, negative parenting practices such as maltreatment and harsh punishment may act as stressors that precipitate suicidality among those who are vulnerable (diathesis) [19]. Simultaneously, robust parenting may act as a protective factor to moderate the negative effects of stressful life events on the development of suicidal ideation [20].

The association between parenting practices and adolescent suicidal behavior continues to be an under-researched area with evidence from high-income countries dominating the available literature. The present review attempts to synthesize the available global evidence and seeks to explore the links between parenting practices, beyond the well-known four parenting styles, and youth suicidal behavior with the goal of enriching the evidence regarding possible risk or protective factors for adolescent suicidal behavior. This may also provide an evidence base for conceptualizing and testing the efficacy of interventions targeting these factors on suicidal behavior in this group.

From this perspective, the major findings of the present review merit a discussion. Firstly, though the bulk of the available evidence implicates the role of authoritarian parenting in suicidal behavior, one study also showed that authoritarian parenting mitigates suicidal risk [21]. It is noteworthy that the latter study found a race and age specific moderating effect of parenting style on children’s suicidal risk; while authoritarian parenting attenuated the relationship between depressive symptoms and suicidal risk among older children and those of Afro-American descent, such a relationship was not true for Caucasian and younger children. This is an important finding which suggests that the effects of parenting practices on suicidal behavior among youth may vary across racial and ethnic settings. On the same token, readers may note earlier research findings suggesting that authoritarian parenting practices foster positive psychological adjustment among poor Afro-American children [22], this is in direct contrast to findings among children in general, including Asian settings [23, 24]. The message here seems to be that, authoritarian parenting may be perceived differently by children of different ethnicities and this may, in turn, yield differential effects on psychological adjustment and suicidal risk among children.

The other parenting style less frequently associated with youth suicidal behavior was permissive parenting. Permissive parenting, particularly paternal, may negatively influence the quality of attachment and emotional bonding with parents, and contribute to the development of suicidal ideation among children [25]. In terms of parental overprotection, one study showed its curvilinear relationship with suicidal ideation; specifically, parental overprotection reduces suicidal ideation only to a certain limit while excessive parental oversight can have deleterious consequences on suicidal behavior [26]. Prior research has shown that overprotective parenting can diminish personal autonomy, reduce self-efficacy, and undermine subjective well-being [27].

In addition, the present review has identified a host of parenting factors such as inconsistent parenting style, parental overprotection, neglect, abuse or maltreatment, low levels of parental warmth and affection, and perceived dissatisfaction with parenting as being linked to adolescent suicidal ideation and behavior. While we have not estimated the strength of these associations, our findings will inform therapeutic and preventive work with adolescents experiencing suicidal ideation as well as their families. Interventions targeting the above parenting factors should be developed and tested for their efficacy in reducing high risk behavior in this group.

In this regard, a recent, influential meta-analysis that sought to quantify the impact of psychological therapeutic interventions in mitigating suicidal and nonsuicidal behavior among adolescents found that effective interventions such as cognitive-behavior therapy and mentalization-based therapy had larger effect sizes when family level interventions were also included [28]. Given this evidence, our results may help to identify parenting practice targets for refining and enhancing the efficacy and effectiveness of therapeutic interventions. Based on available evidence, there is a basis for incorporating positive parenting practices into universal prevention and health promotion strategies through public health messaging and imparting training on good parenting practices [29].

4.1. Strength and Limitations

This is the first initiative to synthesize the available evidence with an aim of determining the association between parenting style and suicidal behavior. However, several limitations should be considered. Firstly, the number of studies was relatively small that hinders the replication and generalization of findings. Secondly, there is an extreme heterogeneity among the studies in regards to the study design, measuring instrument, sample size, and study settings that may challenge the generalization of study results. Thirdly, the role of culture was not adjusted in the studies as parenting style varies from culture to culture. Fourthly, the majority of the studies are from high-income countries that hinder the generalization of results.

5. Conclusions

It can be opined that the association of parenting style and suicidal behavior is an understudied area. Further, well-designed studies are warranted to assess the relationship. This focused review identified the supportive notion that authoritarian and childhood neglects have an association with suicidal behavior in adolescence, and later life. However, a prudential judgment is warranted due to the heterogeneity of study methods, population, contexts, and measurement tools.
