This dataset is based on series of three studies conducted as part of a PhD thesis for the award of Doctor of Philosophy (Clinical Psychology). The thesis investigated the relationship between early maladaptive schemas (EMS) from the schema therapy model and their relationship with interpersonal problems. The dataset for study one is based on a metaanalysis investigating the correlations between early maladaptive schemas and measures of interpersonal relationship problems from the available research as systematically reviewed in 2019. The remaining two datasets were sampled from a first-year psychology student participant pool at the University of New England. The dataset from study two is based on a repeated measures experiment which assessed participant responses and EMS scores following a series of interpersonal vignettes depicting acceptance, ambiguous rejection and rejection. The responses from study two included measures of perceived emotional distress and negative cognitions measured quantitatively and a series of written actions coded qualitatively using inductive content analysis. The dataset from study three consists of crosssectional survey data including measures for EMSs, cognitive emotion regulation strategies, trait-mindfulness and trait-tendencies for problematic interpersonal behaviour patterns. Together these datasets found support for a link between EMSs and low trait-mindfulness, increased emotional distress, negative cognitions and trait-tendencies for problematic interpersonal behaviour patterns.

Early maladaptive schemas (EMSs) have been hypothesized to be associated with interpersonal problems. Furthermore, a stronger contention is that EMSs impact negatively on, or cause, interpersonal problems. The aims of this meta-analysis were (a) to assess the strength of the association between EMSs and interpersonal problems, (b) clarify which EMSs are most strongly associated with interpersonal problems, (c) examine any possible moderators on the relationship between EMSs and interpersonal problems, and (d) examine whether any empirical evidence exists supporting a causal relationship between EMSs and interpersonal problems. A comprehensive systematic literature search and meta-analysis were conducted using the PRISMA guidelines for systematic reviews. A total of 49 empirical studies were reviewed investigating EMSs and interpersonal problems. EMSs were found to have a moderate positive association with interpersonal problems with different EMSs having small to moderate effect sizes. To date, there has been limited evidence supporting a causal effect of EMSs on interpersonal problems. Possible limitations and avenues for future research were discussed.

Background

Early maladaptive schemas (EMSs) have been theorised to contribute to reoccurring interpersonal problems. This study developed a novel experimental paradigm that aimed to assess if EMSs moderate the impact of interpersonal situations on interpersonal responses by manipulating the degree of rejection in a series of interpersonal vignettes depicting acceptance, ambiguous rejection and rejection.

Method

In a sample of 158 first-year psychology students (27.2% male; 72.2% female; 0.6% other) participant responses to interpersonal scenarios were measured including degree of perceived rejection, emotional distress, conviction in varying cognitive appraisals consistent with attribution theory and behavioural responses to scenarios. Qualitative data was analysed using inductive content analysis and statistical analyses were conducted using multilevel mixed effect linear and logistic regression models using the software Jamovi.

Results

People reporting higher EMSs reported increased emotional distress (F(1, 156) = 24.85, p < .001), perceptions of rejection (F(1, 156) = 34.33, p < .001), self-blame (F(1, 156) = 53.25, p < .001), other-blame (F(1, 156) = 13.16, p < .001) and more intentional (F(1, 156) = 9.24, p = .003), stable (F(1, 156) = 25.22, p < .001) and global (F(1, 156) = 19.55, p < .001) attributions but no differences in reported behavioural responses. The results also supported that EMSs moderate the relationship between interpersonal rejection and perceptions of rejection (F(2, 1252) = 18.43, p < .001), emotional distress (F(2, 1252) = 12.64, p < .001) and self-blame (F(2, 1252) = 14.00, p < .001).

Conclusion

Together these findings suggest that people with EMSs experience increased distress and select negative cognitions in situations where there are higher levels of rejection but that distress and negative cognitions are generally higher in people with EMSs irrespective of the situation.

Interpersonal problems are broadly defined as chronic interpersonal performance issues which can comprise of interpersonal distress, unhelpful cognitive appraisals and behavioural responses to interpersonal situations and negative interpersonal outcomes (e.g. divorce). These are distinguished from interpersonal skills deficits which presume a person simply lacks the ability to act appropriately in interpersonal situations (Leising et al., 2011). Interpersonal problems can have adverse impacts on psychological wellbeing and are some of the most common reasons people present for psychological treatment (Mckay et al., 2012). This thesis investigated Young et al's (2003) early maladaptive schemas (EMS) from the schema therapy model and their relationship with interpersonal problems. In particular, this thesis attempted to clarify the existing evidence available for the relationship between EMS and interpersonal problems and develop a greater understanding for how EMS might be associated with interpersonal problems.

Study one aimed to assess the magnitude of the association and potential moderators on the relationship between EMS and interpersonal problems. A total of 49 empirical studies were systematically reviewed and a meta-analysis was performed on reported correlations between EMSs and interpersonal problems using the PRISMA guidelines for systematic reviews. Study one found EMS to have a moderate positive association with interpersonal problems with EMS in the rejection and disconnection domain having the highest correlations with interpersonal problems. The strength of the association between EMS and interpersonal problems was found to be weaker in intimate relationships, when assessed by significant others and when assessing more specific types of interpersonal behaviour (e.g. aggression versus general problematic trait interpersonal tendencies). Limited experimental or longitudinal studies were found supporting a causal relationship between EMS on interpersonal problems.

Study two designed a novel experimental paradigm for assessing the relationship between EMS and interpersonal problems. Study two consisted of 168 university students where degree of rejection was manipulated in a series of interpersonal vignettes. Study two aimed to assess if EMS moderated the casual relationship between different interpersonal contexts and the emotional, cognitive and behavioural responses to those contexts. Rejection was found to predict emotional, cognitive and behavioural responses and people reporting higher EMS reported higher levels of emotional distress and negative cognitions but no differences in behavioural responses. People reporting higher EMS also reported increased emotional distress and select negative cognitions as the degree of rejection in the interpersonal situation increased.

Study three aimed to assess whether EMS are associated with trait tendencies to selectively attend to our environment and whether this was associated with increased interpersonal problems. This aim was achieved by assessing whether trait-mindfulness mediated the relationship between EMS and interpersonal problems. Utilising a sample of 117 university students, study three found both EMS and interpersonal problems to be negatively associated with trait-mindfulness. Decreases in select facets of trait-mindfulness were found to mediate the relationship between EMS and interpersonal problems including reduced tendencies to objectively describe and accept events in our environment without passing judgement.

Together the findings of this thesis present consistent support for an association between EMS and interpersonal problems but find that the strength of this association might vary based on types of interpersonal relationships, measures of interpersonal problems and reporters used to assess interpersonal problems. This thesis provides one of the first experimental methods for assessing the relationship between EMS and interpersonal problems by manipulating the interpersonal situation (e.g. degrees of rejection) and assessing the changes in interpersonal responses to that situation. This thesis also argues that EMS might be associated with interpersonal problems by restricting attention, increasing emotional distress and negative cognitive reactions to interpersonal situations. This thesis found that EMS might be less likely to predict interpersonal behaviour and that interpersonal behaviour is more likely to vary based on the interpersonal situation.
