What the research actually says about the constructs behind our library of instruments, written for anyone who wants to understand the pattern rather than just score it.
Generalized Anxiety Disorder Scale (GADS): Measuring Worry & Metacognition
The Generalized Anxiety Disorder Scale (GADS) is a 4-item self-report instrument developed by Adrian Wells in 1997. It quantifies the core features of Generalized Anxiety Disorder (GAD), focusing on subjective distress, perceived uncontrollability of worry, and metacognitive beliefs. This scale is valuable for assessing GAD severity and informing treatment plans, particularly within Metacognitive Therapy.

The GAD-7 is a brief, 7-item self-report measure for screening and assessing Generalized Anxiety Disorder symptoms. Developed based on DSM-IV criteria, it helps researchers identify symptom severity in individuals aged 14 and older, particularly in primary care settings. It offers a clear cutoff for further clinical evaluation.

The Brief Patient Health Questionnaire (Brief PHQ) is a concise, self-administered screening tool designed for rapid use in primary care and general medical settings. It helps researchers quickly identify and assess the severity of common mental health issues, particularly Major Depressive Disorder and Panic Disorder, informing the need for further evaluation.
Read articlePHQ-15 Somatic Symptom Severity Scale: Measures Physical Complaints
The PHQ-15 Somatic Symptom Severity Scale is a brief, self-administered instrument designed to assess the severity of somatic symptoms in adult populations. Developed by Spitzer, Williams, and Kroenke, it functions as an effective screening tool for potential somatization and somatoform disorders. Researchers can use this scale to quantify the presence and level of bother caused by common physical complaints over the preceding four weeks.
Read articlePHQ-15: Measuring Somatic Symptom Severity in Primary Care
The PHQ-15 Somatic Symptom Scale is a brief, self-administered instrument for rapidly assessing somatic symptom severity in primary care and general medical settings. It helps researchers quantify common physical complaints and identify associated distress or functional impairment. This measure is suitable for studies investigating the prevalence and impact of somatic symptoms in diverse populations.
Read articlePHQ-9: Screening and Severity Measure for Major Depressive Disorder
The Patient Health Questionnaire – Depression (PHQ-9) is a concise, nine-item instrument designed for screening and measuring the severity of Major Depressive Disorder (MDD). Rooted in DSM-IV diagnostic criteria, it is particularly valuable in clinical settings like primary care for identifying potential cases and monitoring treatment response. Researchers can use it to efficiently assess depressive symptoms in study populations.
Read articleAberdeen Low Back Pain Scale: Measuring Impact and Severity
The Aberdeen Low Back Pain Scale is a psychometric instrument designed to quantify the impact and severity of low back pain. Researchers can utilize this scale to assess pain experiences and their functional consequences across various study populations, aiding in the evaluation of interventions or understanding the natural course of low back pain. Its structured format supports consistent data collection in clinical and research settings.
Read articleBeck Depression Inventory (BDI): Measuring Clinical Depression
The Beck Depression Inventory (BDI) is a 21-item self-report instrument designed to quantify the behavioral and symptomatic manifestations of clinical depression. Researchers can utilize the BDI to assess the severity of depressive symptoms in study participants, providing a structured and reliable measure for both clinical and research contexts. It is suitable for studies requiring a robust and established tool for depression assessment.
Read articleAcculturation Scale for Mexican Americans (ASMA)
The Acculturation Scale for Mexican Americans (ASMA) is a brief, 5-item instrument designed to assess acculturation among Mexican Americans through language use and proficiency. Developed in 1985, it is particularly useful for researchers in public health and healthcare seeking to quickly understand cultural adaptation in large samples. This measure helps identify linguistic and cultural factors relevant to research and clinical care.
