Child Maltreatment, Non-Suicidal Self-Injury, and the Mediating Role of Self-Criticism

We examined the relation between child maltreatment and non-suicidal self-injury (NSSI). Participants were 86 adolescents who completed measures of child maltreatment, self-criticism, perceived criticism, depression, and NSSI. Analyses revealed significant, small-to-medium associations between specific forms of child maltreatment (physical neglect, emotional abuse, and sexual abuse) and the presence of a recent history of NSSI. Emotional and sexual abuse had the strongest relations with NSSI, and the data supported a theoretical model in which self-criticism mediates the relation between emotional abuse and engagement in NSSI. Specificity for the mediating role of self-criticism was demonstrated by ruling out alternative mediation models. Taken together, these results indicate that several different forms of childhood maltreatment are associated with NSSI and illuminate one mechanism through which maltreatment may be associated with NSSI. Future research is needed to test the temporal relation between maltreatment and NSSI and should aim to identify additional pathways to engagement in NSSI.Psycholog

Utilization of prescription drugs with warnings of suicidal thoughts and behaviours in the USA and the US Department of Veterans Affairs, 2009

Objectives  To develop a list of prescription medications labelled with warnings for adverse effects of suicidal ideation or behaviour and to describe utilization in the USA and in the Department of Veterans Affairs (VA) in 2009. Methods  A systematic search of US Food and Drug Administration and other references using ‘suicide’, ‘suicidal’ and ‘suicidality’ was used to identify prescription drugs labelled for risk of suicidal ideation or behaviour. Prescription medications sold in the USA by sales volume are reported alongside VA utilization as determined from national electronic pharmacy records. Key findings  One hundred and twenty-five prescription drugs were labelled for potential adverse effects of suicidal ideation or behaviour. Forty-five of these drugs were among the top 200 prescription medications sold in the USA in 2009 with a total sales volume of 540.8 million prescriptions. Rank-ordered utilization was similar in the VA. VA total fill volume was 5.99 million prescriptions. Conclusions  The majority of prescriptions with adverse effect warnings of suicidal ideation or behaviour were generic. Relatively high volumes of drugs with warnings for suicidal ideation or behaviour are filled in the USA and in the VA

Examination of the Relationship between Psychosocial Mediators and Intervention Effects in It’s Your Game: An Effective HIV/STI/Pregnancy Prevention Intervention for Middle School Students

A set of mediation analyses were carried out in this study using data from It’s Your Game. . .Keep It Real (IYG), a successful HIV/STI/pregnancy prevention program. The IYG study evaluated a skill and normbased. HIV/STI/pregnancy prevention program that was implemented from 2004 to 2007 among 907 urban low-income middle school youth in Houston, TX, USA. Analyses were carried out to investigate the degree to which a set of proposed psychosocial measures of behavioral knowledge, perceived self-efficacy, behavioral, and normative beliefs, and perceived risky situations, all targeted by the intervention, mediated the intervention’s effectiveness in reducing initiation of sex. The mediation process was assessed by examining the significance and size of the estimated effects from the mediating pathways. The findings from this study provide evidence that the majority of the psychosocial mediators targeted by the IYG intervention are indeed related to the desired behavior and provide evidence that the conceptual theory underlying the targeted psychosocial mediators in the intervention is appropriate. Two of the psychosocial mediators significantly mediated the intervention effect, knowledge of STI signs and symptoms and refusal self-efficacy. This study suggests that the underlying causal mechanisms of action of these interventions are complex and warrant further analyses
