Commentary tempers causal claims linking family control and suicidal ideation

A commentary on a cross-sectional study of 852 Chinese university students supports an association among parental psychological control, socially prescribed perfectionism, depression and suicidal ideation, while cautioning that the data cannot establish which factors preceded or caused the others. The original research proposed a partial serial mediation model in which parental psychological control was associated with suicidal ideation partly through socially prescribed perfectionism and, subsequently, depressive symptoms. The commentary, published in BMC Psychology as a Matters Arising article, identifies causal wording, the treatment of two suicidal-ideation measures as one score and gaps in statistical reporting as the main reasons for caution.

It reports no new data and conducts no new analyses. The original study examined a population for which suicide is described as a leading cause of death, placing the findings within a broader concern about the mental health of university students. Its framework combines family dynamics with cognitive vulnerability: parental psychological control represents the family-related component, socially prescribed perfectionism represents the cognitive component and depression is positioned as a possible intervening state.

The researchers reported significant indirect associations connecting parental psychological control to suicidal ideation through socially prescribed perfectionism and depression. This observational pattern is potentially informative, but it does not show that control produces perfectionistic beliefs, that those beliefs cause depression or that any of these factors cause suicidal thoughts. That distinction is central to the commentary’s first concern.

In a cross-sectional design, participants report conditions at the same time, so the study cannot establish which factor preceded another. Terms such as “causes,” “leads to” and similar formulations therefore imply temporal precedence and direction that the data did not demonstrate. Alternative sequences remain possible, including a pathway running from depressive symptoms to perfectionistic thinking.

The commentary illustrates this reverse-direction problem with two lines of evidence. A cognitive vulnerability model of depression also proposes that depressive cognitions can activate maladaptive perfectionistic thought patterns. Neither cited line proves that the same sequence operates in the 852-student sample, but both make it inappropriate to treat the proposed order as settled.

A cross-sectional mediation model can organize the observed covariation and test whether indirect paths are statistically supported; it cannot, by itself, turn that organization into a temporal or causal mechanism. Measurement raises a second challenge. The original study used the Positive and Negative Suicidal Ideation Inventory, known by the acronym PANSI, which contains two distinct subscales.

Negative Ideation measures active suicidal cognitions, whereas Positive Ideation captures reasons for living and protective cognitions. By reverse-scoring the positive items and combining both sets into one composite, the analysis treats protection and danger as opposite ends of a single continuum. The commentary notes that previous research has shown these subscales can have different relationships with risk and protective factors, including distinct associations among perfectionistic people.

That methodological choice may conceal an important result. If parental psychological control or socially prescribed perfectionism is associated more strongly with increased negative ideation, weaker protective positive ideation, or both, a composite score would not reveal the pattern. The same concern applies to perfectionism: mechanisms involving risk and protection may not operate at identical levels.

The commentary therefore asks for analyses that keep the two subscales separate or, at minimum, for clearer justification of the decision to combine them. Such analyses would not prove causation, but they could clarify whether the statistical relationship is concentrated in thoughts of death, reduced reasons for living, or a combination of the two. The commentary also finds that the original article devoted less discussion to one prominent part of the model than to the more elaborate mediation chain.

The direct association between parental psychological control and suicidal ideation reportedly accounted for 58.8% of the total relationship, whereas the partial serial mediation through socially prescribed perfectionism and depression accounted for 13.6%. The indirect path is scientifically interesting, especially because it links family influence, perfectionistic cognition and depressive symptoms within one model. Still, the larger direct share means that most of the observed association remained outside the proposed indirect sequence.

The commentary argues that this unaccounted portion deserved more attention in the discussion rather than being overshadowed by the chain mediation. A further reporting issue arises because the standardized coefficient for the indirect path through socially prescribed perfectionism was identical to that of the full serial chain, both given as β = 0.035 and 13.6% of the association. This creates uncertainty about how much the addition of depression contributes beyond the simpler pathway.

The commentary recommends comparing the competing models with a fit measure such as the Akaike Information Criterion, or AIC, which can help readers assess whether the more complex chain provides enough additional explanatory value to justify its greater complexity. Equal coefficients do not by themselves show that depression is irrelevant, but they make direct model comparison important for interpreting the incremental contribution of the serial pathway. The original data collection included several potential moderators, including gender, academic year, family economic condition and parental education level.

The commentary proposes examining whether these characteristics alter the relationships among psychological control, perfectionism, depression and suicidal ideation. Gender receives particular attention because prior work cited in the commentary found that it moderated depression through distinct affective and cognitive routes, with parental psychological control and suicidal ideation representing one route and socially prescribed perfectionism another. Moderation analyses could therefore test whether the same pattern applies across groups or differs meaningfully among students.

The commentary presents this as a way to enrich the findings, not as evidence that any subgroup has already been shown to experience a different pathway. Overall, the original study is described as a genuine contribution because it examines a consequential mental-health outcome in a large student sample and brings family relationships and perfectionistic cognition into a single, theoretically coherent framework. The commentary’s recommended changes—more consistently associational language, separate analysis of positive and negative suicidal ideation, fuller treatment of the large direct association and stronger comparison of nested models—would narrow the gap between what the data show and what the conclusions claim.

The results are best read as evidence of interconnected variables in one cross-sectional sample, not as proof of an inevitable progression from parental control to perfectionism, depression and suicidal thoughts. The study therefore offers a useful map of statistical relationships while leaving the direction, mechanisms and boundary conditions of those relationships unresolved.
