The Adult ADHD Self Report Scale (ASRS v1.1) was developed by a World Health Organization workgroup, with Lenard Adler, Ronald Kessler and Thomas Spencer, and published in 2005.

It has two parts. The full Symptom Checklist has 18 items mapped to the DSM-IV ADHD criteria and reworded for adult presentations. The six question screener, drawn from Part A, is the subset that best predicts ADHD and is the version most people mean when they say ASRS.

The Adult Repetitive Behaviours Questionnaire (RBQ-2A) is a 20 item self report measure of restricted and repetitive behaviours in adults.

It was developed by Sarah Barrett, Mirko Uljarevic, Susan Leekam and colleagues and published in 2015, adapted from the caregiver reported RBQ-2. It is published open access under a Creative Commons licence, which makes it one of the more permissively licensed instruments in this area.

The Adverse Childhood Experiences (ACE) assessment is a tool used to identify the presence and impact of negative experiences in childhood. It is a simple scoring method that tallies various types of abuse, neglect, and household challenges faced during childhood. The ACE assessment helps in understanding the cumulative effect of these experiences on a person's health and well-being.

The ACE assessment was developed from the Adverse Childhood Experiences Study, a large-scale investigation conducted by the Centers for Disease Control and Prevention and Kaiser Permanente. Dr. Vincent Felitti and Dr. Robert Anda led the study in the 1990s, focusing on the long-term effects of childhood trauma.

The Alcohol Use Disorders Identification Test (AUDIT) is a widely recognised screening tool used to identify individuals with risky or hazardous alcohol consumption patterns as well as those with established alcohol use disorders. It is designed to prompt an early response in primary care settings and is sensitive to the full spectrum of alcohol problems.

Developed by the World Health Organization (WHO) in 1982, the AUDIT was the result of a multinational collaborative project. It was created to detect alcohol problems experienced within the past year, providing a framework for intervention to reduce or prevent harmful consequences.

The Altman Self-Rating Mania Scale (ASRM) is a concise, self-report instrument designed to assess the presence and severity of manic or hypomanic symptoms. Comprising just 5 items, the ASRM is valued for its brevity and ease of use in both clinical and research settings.

Developed by Dr. Sidney Altman, this scale was designed to provide a quick and effective tool for assessing mania. The ASRM aligns with the CARS-M, YMRS, and DSM-IV diagnostic criteria, enhancing its utility as a screening and diagnostic instrument.

The Australian Treatment Outcomes Profile (ATOP) is a concise and effective tool designed to evaluate the impact of substance use treatment on individuals. It is a 22-item instrument focusing on assessing various parameters of substance use and general health and wellbeing over the preceding four weeks.

Developed in Australia, ATOP was designed with the intention to provide a standardised method for monitoring treatment outcomes in substance use. The assessment tool was created to capture the multifaceted nature of substance abuse treatment outcomes, recognising the importance of both substance use and overall wellbeing. It is a patient reported outcome measure (PROM) and clinical risk screening tool, eliciting responses directly from clients and is designed to be incorporated into routine clinical care in Alcohol and other Drug (AoD) treatment settings.

The Autism Spectrum Quotient (AQ) is a self-assessment tool designed to measure the severity of autism spectrum traits in adults. It consists of 50 questions, each allowing the respondent to indicate the degree to which they agree or disagree with a given statement. This assessment focuses on five different areas: social skills, attention switching, attention to detail, communication, and imagination.

The AQ was developed by Simon Baron-Cohen and his colleagues at the Cambridge Autism Research Centre, first published in 2001. Its creation was driven by the need for a quick, reliable, and quantifiable measure of autism spectrum traits in adults.

The Autism Spectrum Screening Questionnaire (ASSQ) is a 27 item parent or teacher report screener for autism in school aged children and young people.

It was developed by Stephan Ehlers, Christopher Gillberg and Lorna Wing and published in 1999. It is maintained by the Gillberg Neuropsychiatry Centre at the University of Gothenburg.

The Centre prohibits digitisation of the ASSQ, and access is moving to a paid licensing arrangement. Any digital use requires a licence.

The Beck Anxiety Inventory (BAI) is a 21 item self report measure of anxiety severity.

It was developed by Aaron Beck, Norman Epstein, Gary Brown and Robert Steer and published in 1988. It was designed specifically to measure anxiety with minimal overlap with depression, which is why it leans heavily on somatic and panic like symptoms.

The BAI is a registered trademark of Pearson and is a commercially licensed instrument.

The Beck Depression Inventory (BDI) is a highly regarded self-report inventory designed to assess the presence and severity of depressive symptoms. Developed in several versions, including BDI, BDI-1A, and the more recent BDI-II, it consists of 21 questions, each with multiple-choice answers. The BDI is celebrated for its simplicity and efficiency in clinical settings.

Created by psychiatrist Aaron T. Beck, the BDI was initially published in 1961, with subsequent revisions in 1971 (BDI-1A) and 1996 (BDI-II). Beck's development of the inventory was part of a larger shift in psychiatry towards cognitive theory, focusing on how a person's thoughts and beliefs influence their mood and behavior.

The Bergen Shopping Addiction Scale (BSAS) is a seven item self report measure of problematic shopping behaviour.

It was developed by Cecilie Andreassen, Mark Griffiths, Stale Pallesen and colleagues and published open access in Frontiers in Psychology in 2015. It was validated in a Norwegian sample of over 23,000 adults and covers both online and offline shopping deliberately.

The Big Five Personality Test, based on the Five-Factor Model (FFM), is a widely acknowledged personality assessment tool. It evaluates five major dimensions of human personality: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism (OCEAN).

Developed through the collaborative efforts of various personality psychologists in the early 1990s, the Big Five Personality Test evolved from common language descriptors to a structured psychological model. It represents a significant advancement in the understanding of personality.

The Binge Eating Scale (BES) is a specialised 16-item questionnaire designed to identify the presence and severity of binge eating behaviours that could indicate an eating disorder. This self-report tool is vital in both clinical and research settings for understanding binge eating patterns.

The BES was developed to specifically address the need for an effective tool to assess binge eating behaviors, which are key indicators of certain eating disorders. This scale provides a focused approach to understanding the behavioural and emotional aspects of binge eating.

The Buss Perry Aggression Questionnaire (BPAQ) is a 29 item self report measure of trait aggression.

It was developed by Arnold Buss and Mark Perry and published in 1992. It is the most widely used self report aggression measure in research, and it separates aggression into behavioural, emotional and cognitive components.

Note that it is distinct from the commercially published Aggression Questionnaire by Buss and Warren, which has 34 items and is licence restricted.

The CAGE Alcohol Questionnaire is a brief and widely used screening tool for identifying potential alcohol problems. It consists of just four questions, designed to be easy to administer and interpret. The focus of CAGE is on identifying problematic drinking behaviours and patterns that might indicate alcohol abuse or dependence.

Developed by Dr. John A. Ewing, founder of the Bowles Center for Alcohol Studies at the University of North Carolina at Chapel Hill, the CAGE questionnaire was introduced in the 1970s. Its purpose was to provide a straightforward and effective method for identifying individuals who might benefit from further alcohol dependency evaluation.

The Camouflaging Autistic Traits Questionnaire (CAT-Q) is a 25-item self-report instrument designed to assess the extent to which individuals employ camouflaging strategies to mask or compensate for autistic traits in social contexts.

Developed by Laura Hull and colleagues in 2018, the CAT-Q emerged from qualitative research involving autistic adults, aiming to quantify the phenomenon of social camouflaging—a set of behaviors used to conceal autistic characteristics to fit into social environments.

The Childhood Autism Spectrum Test (CAST), formerly known as the Childhood Asperger’s Syndrome Test, is a parent-reported questionnaire designed to identify autism spectrum symptoms in children. Comprising 39 items, this test uses simple 'yes' or 'no' responses to evaluate behavioural and developmental characteristics associated with autism spectrum disorders.

Developed by the Autism Research Centre (ARC) at the University of Cambridge, the CAST was designed to be a practical and accessible tool for early screening of autism spectrum conditions. Its development reflects a broader effort to enhance early detection and intervention in autism research and care.

The Chronic Pain Acceptance Questionnaire – Revised (CPAQ-R) is a 20-item instrument designed to assess the degree of acceptance individuals have regarding their chronic pain. Acceptance in this context refers to the willingness to experience pain without trying to control or avoid it, allowing individuals to focus more on valued life activities and goals.

The CPAQ-R is an updated version of the original CPAQ, offering improved reliability and validity. It was developed by researchers in the field of chronic pain to better understand and measure the concept of pain acceptance.

The Client Motivation for Therapy Scale (CMOTS) is a psychometric tool designed to measure a client's motivation for therapy. It assesses various dimensions of motivation, including Intrinsic Motivation, four forms of Extrinsic Motivation (integrated, identified, introjected, and external regulation), and Amotivation.

Developed by researchers in the field of psychology, the CMOTS is grounded in Self-Determination Theory. It is used to understand the motivational factors that influence a client's engagement in therapy.

The Clinical Global Impression (CGI) is a pair of single item clinician ratings: one for how ill the person is now, and one for how much they have changed since treatment began.

It was published in the NIMH ECDEU Assessment Manual for Psychopharmacology, edited by William Guy, in 1976. It is one of the most widely used measures in psychiatric research, and it takes under a minute.
