CAT-PD: Depressiveness – Personality Trait Assessment & Reflection Bundle (CAT-PD-DEP)

Do you carry a persistent undercurrent of sadness, self-doubt, or hopelessness — not as a passing mood, but as a familiar companion?

The CAT-PD: Depressiveness Worksheet Bundle (CAT-PD-DEP) is a research-validated self-reflection toolkit designed to help you identify, understand, and begin working with trait-level depressiveness — the chronic personality patterns of low mood, negative self-evaluation, and pessimism that quietly shape how you see yourself and the world.

Unlike general depression questionnaires that measure episodes or symptoms, this tool is based on the Computerized Adaptive Testing of Personality Disorders – Short Form (CAT-PD-SF), developed by Simms and colleagues, with strong psychometric reliability (Cronbach's alpha = .88). It captures depressiveness as a stable personality dimension — distinct from clinical diagnoses — aligned with the DSM-5 Section III Alternative Model for Personality Disorders.

What You Get: 6 Structured Worksheets

WS 1 — Introduction & Assessment Items

A clear explanation of what depressiveness means at the trait level, how this tool was developed, and the complete set of 6 self-report items with a 5-point rating scale. Includes preparation guidance and a full rating scale legend to ensure accurate, honest responses.

WS 2 — Scoring Worksheet

A step-by-step scoring guide that walks you through transferring your item scores, applying reverse-scoring for relevant items, calculating your total mean score, and interpreting your result using a two-level scoring framework (Standard vs. Elevated trait pattern). Includes a visual score profile chart.

WS 3 — Psychoeducation Guide

A deep-dive into the science of personality-level depressiveness — what the research says, how it affects daily life across common situations, the neurobiological and psychological factors involved, protective factors you can build on, and a myth-versus-fact table that separates clinical reality from common misconceptions. Includes guided self-reflection questions.

WS 4 — Personal Action Plan for Emotional Balance

A structured planning worksheet to move from insight to change. Includes SMART goal-setting across three domains (daily awareness, cognitive patterns, social engagement), a 7-day weekly implementation planner, an obstacle-and-solution table, a support system map, and a 4-week progress tracker.

WS 5 — Clinician Reference Guide

A professional-level reference sheet covering the theoretical framework, psychometric properties, scoring and interpretation thresholds, differential diagnostic considerations (including ruling out medical causes and comorbid traits), and a curated evidence base with peer-reviewed citations. Designed for therapists, counselors, and researchers using this tool in clinical or academic contexts.

WS 6 — Informed Consent Form

A printable consent document outlining the nature, purpose, confidentiality, voluntary participation terms, benefits and risks, and confirmation checkboxes — suitable for use in both personal and professional settings.

Who This Bundle Is For

• Individuals who want to understand whether their tendency toward sadness, self-criticism, or hopelessness reflects a deeper personality pattern — not just a bad week
• People in therapy or personal development work who want structured tools to complement their process
• Psychology students and researchers needing a validated, accessible self-report measure of depressiveness as a personality trait
• Counselors, therapists, and clinicians looking for a psychoeducation and assessment supplement for clients exploring personality-level emotional patterns
• Anyone interested in applied personality psychology and evidence-based self-reflection

What Makes This Different

This is not a mood diary or a wellness checklist. The CAT-PD-DEP bundle is grounded in validated personality science, aligned with the DSM-5 Section III trait model, and designed to distinguish between temporary emotional states and enduring dispositional patterns. Every worksheet builds on the previous one — from assessment to understanding to action — making this a complete, end-to-end toolkit rather than a standalone quiz.

Your responses remain entirely private. This is a print-and-use resource. No data is collected, stored, or shared.

Important Note

This bundle is an educational and self-reflection tool. It is not a diagnostic instrument and does not replace professional psychological evaluation. If you have concerns about your mental health, please consult a qualified mental health professional.
