Prevention of Burnout in Spanish Healthcare Professionals Through Attachment-Based Compassion Therapy (ABCT)

In the compassion program group. Burnout will be assessed using the Maslach Burnout Inventory Human Services Survey. This questionnaire evaluates three main dimensions of burnout in healthcare professionals: emotional exhaustion, depersonalization, and personal accomplishment. Each item is scored on a Likert-type scale ranging from 0 to 6, where 0 indicates "never or almost never" and 6 indicates "almost always or always". Participants rate the frequency with which they experience each symptom. Higher scores on emotional exhaustion and depersonalization indicate a worse outcome, reflecting higher levels of burnout. Higher scores on personal accomplishment indicate a better outcome, whereas lower scores indicate reduced personal accomplishment and a worse outcome.

In the compassion program group. Clinical burnout subtypes will be assessed using the Burnout Clinical Subtype Questionnaire-12. This questionnaire evaluates three burnout profiles in healthcare professionals: overload, lack of development, and neglect/wear-out. It includes 12 items distributed across these three dimensions, with four items per dimension. Each item is scored on a Likert-type scale ranging from 0 to 6, where 0 indicates "totally disagree" and 6 indicates "totally agree". Participants select the response that best reflects how frequently they have experienced each statement. Item scores are summed separately for each subscale, obtaining a raw score for each dimension. Higher scores indicate a greater presence of the corresponding burnout subtype and therefore a worse outcome.

In the compassion program group. Satisfaction and frustration of basic psychological needs will be assessed using the Basic Psychological Needs Satisfaction in General Scale. This self-report scale includes 16 items and evaluates three fundamental psychological needs: autonomy, competence, and relatedness. Each item is scored on a Likert-type scale ranging from 1 to 7, where 1 indicates "totally disagree" and 7 indicates "totally agree".

In the compassion program group. Satisfaction with the treatment received will be assessed using the Treatment Received Satisfaction Scale. This self-report scale includes 4 items designed to evaluate whether participants are satisfied with the intervention received and whether they perceive it as effective. Items 1 and 2 are answered using five response options, while items 3 and 4 are answered using four response options. The scale provides three specific components: satisfaction, problem resolution, and perceived emotional change. A global score is calculated from these components according to the formula proposed by the authors. The global score ranges from 0 to 300, with higher scores indicating greater perceived treatment effectiveness and therefore a better outcome.

In the relaxation program group. Satisfaction with the treatment received will be assessed using the Treatment Received Satisfaction Scale. This self-report scale includes 4 items designed to evaluate whether participants are satisfied with the intervention received and whether they perceive it as effective. Items 1 and 2 are answered using five response options, while items 3 and 4 are answered using four response options. The scale provides three specific components: satisfaction, problem resolution, and perceived emotional change. A global score is calculated from these components according to the formula proposed by the authors. The global score ranges from 0 to 300, with higher scores indicating greater perceived treatment effectiveness and therefore a better outcome.

In the compassion program group. Sensory processing sensitivity will be assessed using the Reduced Highly Sensitive Person Scale to the Adult Spanish Population. This self-report scale includes 16 items designed to evaluate sensitivity in Spanish-speaking adults and to explore how sensitivity may influence different aspects of daily life and psychological well-being. Each item is scored on a Likert-type scale ranging from 0 to 7, where 0 indicates "totally disagree" and 7 indicates "totally agree". Participants select the response that best reflects their experience. Item scores are summed and divided by the number of items to obtain the final score. Higher scores indicate greater sensory processing sensitivity.
