RESUMO
Background: Thwarted Belongingness (TB) and Perceived Burdensomeness (PB) are considered risk factors of suicide behavior in the Interpersonal Theory of Suicide and constitute the main factors of the Interpersonal Needs Questionnaire-INQ. Aims: The present study analyzes the internal consistency, construct validity, and invariance across sex and age of the INQ-15, which comprises two subscales, in a sample of Spanish community adolescents. Methods: Participants were 1,536 adolescents from 12 to 19 years old. The INQ-15, the total number of non-suicidal self-injuries (NSSI), the Hopelessness Scale, and the Purpose in Life Test-Adolescents (PIL-A) were used. Results: The INQ-15 showed good internal consistency for TB ( ω ¯ = 0.88) and PB ( ω ¯ = 0.78) subscales and construct and concurrent/discriminant validity in the whole sample. Both the PB and TB subscales showed a good fit { S B χ 2 ( 9 ) = 6.448, p = 0.694, CFI = 1.000, RMSEA = 0.000 [90% CI (0.000, 0.022)] and S B χ 2 ( 27 ) = 248.973, p = 0.000, CFI = 0.922, RMSEA = 0.073 [90% CI (0.065, 0.082)]}, respectively. Regarding the invariance analyses, we found (1) non-invariance in the PB subscale across sex groups and metric, scalar, and stric invariance across age groups, and (2) that it was not possible to perform the invariance analysis for the TB subscale across both sex and age because the fit was not adequate for both boys and 12-15 years old groups. Positive and significant relationships were found between the INQ-15 subscales and hopelessness and NSSI frequency, and negative and significant correlations with meaning in life. Conclusions: The INQ-15 is a valid instrument for assessing TB and PB in Spanish adolescents. Future studies should analyze the invariance of this instrument in adolescents across sex and age.
RESUMO
BACKGROUND: Adolescence is a developmental stage when there is a high risk of engaging in non-suicidal self-injury (NSSI). There is recent interest in the study of thwarted belongingness and perceived burdensome as variables associated with the frequency of NSSI in adolescents. Meaning in life (MIL) might be negatively associated with thwarted belongingness and perceived burdensomeness. To date, no studies have analyzed the buffering role of MIL in the association between thwarted belongingness and perceived burdensomeness and the frequency of lifetime NSSI in Spanish adolescents. AIMS: (a) To test whether thwarted belongingness and perceived burdensomeness are associated with frequency of lifetime NSSI; (b) to test whether MIL moderates the association between thwarted belongingness and frequency of lifetime NSSI; and (c) to test whether MIL moderates the association between perceived burdensomeness and frequency of lifetime NSSI. METHOD: The sample consisted of N = 1531 participants (n = 736, 48.1%, were men, and n = 795, 51.9%, were women) between 12 and 18 years old from Spain. The participants filled out the Inventory of Statements about Self-Injury, Purpose-In-Life Test-Adolescent Version, and Interpersonal Needs Questionnaire. Moderation analyses were performed. RESULTS: No statistically significant differences were found in the frequency of lifetime NSSI in the adolescents based on gender. Thwarted belongingness and perceived burdensomeness were positively associated with the frequency of lifetime NSSI in Spanish adolescents. MIL was a moderating variable between thwarted belongingness and the frequency of lifetime NSSI, and between perceived burdensomeness and the frequency of lifetime NSSI. CONCLUSIONS: Thwarted belongingness and perceived burdensomeness might be positively associated with the frequency of lifetime NSSI, and MIL might be negatively associated with the frequency of lifetime NSSI. Thus, adding these variables to current descriptive theories of NSSI in adolescents would allow us to improve assessment and treatment protocols for adolescents with NSSI.
RESUMO
OBJECTIVE: The purpose of the present study was threefold: first, to analyse the psychometric properties of a 10-item Spanish version of the Purpose in Life Test, which assesses meaning in life (MiL), in a sample of community adolescents; second, to analyse the differences between the age and gender groups; and third, to analyse whether MiL buffers the relationship between emotional dysregulation and hopelessness. METHOD: Participants were 1,599 adolescents from 12 to 19 years old, M = 15.69, SD = 2.14. The Purpose in Life Test-10 Items, the Beck Hopelessness Scale, and the Difficulties in Emotional Regulation Scale were used. RESULTS: A nine-item version showed good fit, psychometric properties (internal consistency, construct, and concurrent validity), and factorial invariance across gender and age (12-15 years/16-19 years). Difference in MiL between boys and girls was not significant, whereas between age groups was significant. MiL had a strong buffering effect on the relationship between emotional dysregulation and hopelessness. DISCUSSION: It is desirable to promote the sense of MiL in adolescents. MiL plays a significant and strong mediator role in the relationship between emotional dysregulation and hopelessness, reinforcing the positive role of MiL in mental health and as a resource for facing adversity.
