Prevention of Relapse in Behavioral Disorders

To objectively identify episodes of relapse (e.g., alcohol or other substance use) during treatment, periodic toxicological screenings will be performed as part of the therapeutic monitoring process. These screenings are conducted by clinical personnel and include urinalysis: detection of recent use of psychoactive substances through urine samples, providing an objective measure of treatment adherence.

To objectively identify episodes of alcohol relapse during treatment, periodic toxicological screenings will be conducted as part of the therapeutic monitoring process. These screenings will be carried out by clinical staff and will include Breath Alcohol Testing: measurement of breath alcohol concentration using spirometry-based devices to detect recent alcohol consumption.

A 26-item instrument assessing perceived quality of life across four domains: physical health, psychological well-being, social relationships, and environmental context. Items are rated on a 5-point Likert scale, and domain scores are transformed to a 0-100 scale. Demonstrates good internal consistency, with Cronbach's alpha ranging from 0.69 (physical) to 0.90 (spirituality/religion/personal beliefs).

A 10-item self-report scale assessing life purpose and personal meaning, adapted from the original PIL (Crumbaugh & Maholick, 1969). Responses are rated on a 7-point Likert scale, with total scores ranging from 10 to 70. Higher scores reflect greater perceived purpose. The scale includes two dimensions: (a) life satisfaction and meaning, and (b) goals and direction. Shows good psychometric properties (α = .85 overall; .84 for life satisfaction and .69 for goals and purpose).

A 9-item self-report tool assessing depressive symptom severity over the past two weeks, based on DSM-IV criteria. Each item is scored from 0 (not at all) to 3 (nearly every day), yielding a total score of 0-27. A cut-off score of 10 yields sensitivity of 0.78 and specificity of 0.87. Spanish versions show excellent reliability (α = 0.78-0.90), with current data showing α = .93.

25 items self-report questionnaire designed to assess maladaptive beliefs related to substance use and beliefs about substance craving. Each item is rated on a 5-point Likert scale ranging from "totally disagree" to "totally agree". Higher total scores reflect stronger dysfunctional beliefs associated with substance use (e.g., perceived benefits or inevitability of use). The instrument shows excellent internal consistency (Cronbach's alpha = 0.87).

27-item ad hoc questionnaire using a 5-point Likert scale (scale from 1 to 5, with 1 being "Not at all" and 5 being "Very much") to assess patient satisfaction with the application's usability, safety, and overall experience. Higher scores indicate greater satisfaction.
