Note: Within each row, means with the same letter superscript do not differ significantly from one another according to a series of one-way ANOVAs and non-parametric Kruskal-Wallis tests with a Bonferroni correction of p = 0.006. Effect sizes were not produced in the Kruskal-Wallis tests. CTI-C = Cognitive Triad Inventory-Children; CNCEQ = Children’s Negative Cognitive Error Questionnaire; NASSQ = Negative Affect Self-Statement Questionnaire; SOCSS = Survey of Children’s Social Support; NSSI+SA = history of non-suicidal self-injury and suicide attempt; NSSI = history of non-suicidal self-injury without a history of suicide attempt; SA = history of suicide attempt without a history of non-suicidal self-injury;

= statistically significant difference (p < 0.006).
