An Exploratory Study of the Mental Toughness Psychological Skills Profile Psychometrics,and the Mediating Effect of Social Support Sources on Mental Toughness and Suicidal Ideation Among Military Police

Research suggests that social support and mental toughness (i.e., the ability to effectively cope with stress despite adversity and/or failure) may be associated with decreased suicide risk, although methods for measuring mental toughness remain largely undeveloped. The relationship remains largely unknown. In response to this research gap, the psychometric properties of the Mental Toughness Psychological Skills Profile (MTPSP; Asken 2005), and its association with suicide ideation, were evaluated in a sample of active duty U.S. Air Force Security Forces personnel, a subpopulation especially vulnerable to suicide risk. 273 participants from two Air Force bases completed self-report scales including the MTPSP. Results indicated that the MTPSP is comprised of five subscales: Negative Mindset, Positive Mindset, Confidence, Achievement, and Health Behaviors. All five MTPSP factors were independently correlated with general distress, somatic anxiety, positive affect, presence of meaning in life, search for meaning in life, positive self-bias, social support sources, and suicide ideation. The Confidence factor was the only factor that had a significant association with suicide ideation when all five factors were considered simultaneously (β?=??0.18, p?=?.016), but was fully mediated by social support (β?=??0.17, p?=?.033). Self-confidence may be associated with reduced suicide risk because those individuals tend to report higher social support.
