Social support as a protective factor in suicide: two studies from American and English nationally representative samples
Suicide is a problem of great concern worldwide. For example, among all age groups it is the tenth leading cause of death in the United States (Centers for Disease Control and Prevention, 2012) and the fifth leading cause of death in England and Wales (Office for National Statistics, 2012). Moreover, it is the number one preventable (non-accidental) cause of death in some age groups in these countries. Furthermore, suicide currently represents 1.8% of the total worldwide burden of disease (
Participants
Data for the study come from the National Comorbidity Study-Replication (NCS-R; Kessler et al., 2004a, Kessler et al., 2004b, Kessler and Ustün, 2004c), a United States nationally representative sample conducted between 2001 and 2003 of English speaking residents over the age of 17. Weighting procedures for the study data were used according to the guidelines of Kessler et al., 2004a, Kessler et al., 2004b, Kessler and Ustün, 2004c. Of the participants, 4.1% had attempted suicide at some point
Results and discussion
Table 1 presents the results of a logistic regression analysis predicting lifetime suicide attempter status after covarying relevant demographic variables, psychiatric history, family of origin variables, and help seeking behaviors. First, lower age, lower education, and female gender were all associated with higher likelihood of a lifetime suicide attempt. With the exception of drug dependence and specific phobia, all psychiatric disorders were associated with higher likelihood of a lifetime
Participants
Data for the study come from the 2007 Adult Psychiatric Morbidity Survey (APMS; McManus et al., 2009), an English nationally representative sample conduced from October, 2006 to December, 2007 of residents over the age of 16. Weighting procedures for the study data were used according to the guidelines of McManus et al. (2009). The participants in the study were 56.8% female and ranged from 16 to 95 years of age (M=46.35, SD=18.60). The ethnic origin of the sample was 89.6% White, 3.0% Black,
Results and discussion
Table 2 shows the results of a logistic regression analysis predicting lifetime suicide attempts controlling for relevant demographics, psychiatric history, family of origin variables, and help seeking behaviors. Lower age and female gender predicted greater likelihood of a lifetime suicide attempt. With the exception of eating disorders, social phobia, and anti-social personality disorder, all psychiatric history variables were associated with greater likelihood of a lifetime suicide attempt.
General discussion
Suicide is a problem of worldwide concern and there is a need for more research on protective factors in suicide. One such potential factor is social support. We presented a series of studies using nationally representative data that examine the role of social support as a protective factor in suicide. We found that controlling for a variety of relevant predictors, social support was associated with lower likelihood of having a lifetime suicide attempt. In the first study using an American
