abstract="Despite the prominence of the capability-for-suicide construct in suicide research, fundamental hypotheses about its nature and development remain largely untested. In this study, we tested the primary mechanism proposed to account for its development: habituation to painful or provocative events. More than a thousand adults were recruited worldwide from online suicide, self-injury, and mental health web forums and subsequently followed for 28 days. Analyses examined the experiences purported to have the strongest effects: suicidal and nonsuicidal-self-injurious behaviors. Capability was measured explicitly and implicitly. Multiple mediation was used to test whether changes in capability between baseline and 28-day follow-up were accounted for by exposure to self-injurious behaviors that occurred over the intervening time interval. <br><br>RESULTS failed to support the habituation hypothesis, at least as studied within the methodological constraints of this study. Post hoc power analyses indicated ample power to detect small effects. <br><br>RESULTS raise questions about the validity of the habituation hypothesis. © The Author(s) 2020.<p /><p>Language: en</p>",
