In psychology, trait theory is an approach to the study of human personality. Trait theorists are primarily interested in the measurement of traits, which can be defined as habitual patterns of behavior, thought, and emotion. According to this perspective, traits are aspects of personality that are relatively stable over time, differ across individuals, are relatively consistent over situations, and influence behaviour. Traits are in contrast to states, which are more transitory dispositions.
The Beck Depression Inventory, created by Aaron T. Beck, is a 21-question multiple-choice self-report inventory, one of the most widely used psychometric tests for measuring the severity of depression. Its development marked a shift among mental health professionals, who had until then, viewed depression from a psychodynamic perspective, instead of it being rooted in the patient's own thoughts.
Night eating syndrome (NES) is an eating disorder, characterized by a delayed circadian pattern of food intake. Although there is some degree of comorbidity with binge eating disorder, it differs from binge eating in that the amount of food consumed in the night is not necessarily objectively large nor is a loss of control over food intake required. It was originally described by Albert Stunkard in 1955 and is currently included in the other specified feeding or eating disorder category of the DSM-5. Research diagnostic criteria have been proposed and include evening hyperphagia and/or nocturnal awakening and ingestion of food two or more times per week. The person must have awareness of the night eating to differentiate it from the parasomnia sleep-related eating disorder (SRED). Three of five associated symptoms must also be present: lack of appetite in the morning, urges to eat at night, belief that one must eat in order to fall back to sleep at night, depressed mood, and/or difficulty sleeping.
The Eating Attitudes Test, created by David Garner, is a widely used 26-item, standardized self-reported questionnaire of symptoms and concerns characteristic of eating disorders. The EAT is useful in assessing "eating disorder risk" in high school, college and other special risk samples such as athletes. EAT has been extremely effective in screening for anorexia nervosa in many populations.
Sexuality can be inscribed in a multidimensional model comprising different aspects of human life: biology, reproduction, culture, entertainment, relationships and love.
The Eating Disorder Inventory (EDI) is a self-report questionnaire used to assess the presence of eating disorders, (a) anorexia nervosa both restricting and binge-eating/purging type; (b) bulimia nervosa; and (c) eating disorder not otherwise specified including binge eating disorder. The original questionnaire consisted of 64 questions, divided into eight subscales. It was created in 1984 by David M. Garner and others. There have been two subsequent revisions by Garner: the Eating Disorder Inventory-2 (EDI-2) and the Eating Disorder Inventory-3 (EDI-3).
The Binge Eating Scale is a sixteen item questionnaire used to assess the presence of binge eating behavior indicative of an eating disorder. It was devised by J. Gormally et al. in 1982 specifically for use with obese individuals. The questions are based upon both behavioral characteristics and the emotional, cognitive response, guilt or shame.
The Anorectic Behavior Observation Scale (ABOS) is a thirty-item diagnostic questionnaire devised to be answered by the parents, spouse or other family member of an individual suspected of having an eating disorder. It was developed by Vandereyken et al. in 1992. The ABOS is useful for evaluations of patients with anorexia nervosa (AN) and bulimia nervosa (BN) before, during, and after clinical treatments. It can also be a significant tool for the screening of subjects in early-stage ED.
The Eating Disorder Diagnostic Scale (EDDS) is a self-report questionnaire that assesses the presence of three eating disorders; anorexia nervosa, bulimia nervosa and binge eating disorder. It was adapted by Stice et al. in 2000 from the validated structured psychiatric interview: The Eating Disorder Examination (EDE) and the eating disorder module of the Structured Clinical Interview for DSM-IV (SCID)16.
The figure rating scale (FRS), also known as the Stunkard scale, is a psychometric measurement originally developed in 1983 to communicate about the unknown weights of a research subject's absent relatives, and since adapted to assess body image.
Research into food choice investigates how people select the food they eat. An interdisciplinary topic, food choice comprises psychological and sociological aspects, economic issues and sensory aspects.
The Bipolar Spectrum Diagnostic Scale (BSDS) is a psychiatric self-rating scale created by Ronald Pies in screening for bipolar disorder (BD). Its initial version consists of a descriptive narrative aimed to capture the nuances and milder variants of BD. Upon revision by Nassir Ghaemi and colleagues, the scale was developed into two sections for a total of 20 questions. The BSDS is widely accepted as an important measure of bipolar disorder alongside other diagnostic tools such as the Mood Disorder Questionnaire and the Bipolar Depression Rating Scale.
The Patient Health Questionnaire (PHQ) is a multiple-choice self-report inventory that is used as a screening and diagnostic tool for mental health disorders of depression, anxiety, alcohol, eating, and somatoform disorders. It is the self-report version of the Primary Care Evaluation of Mental Disorders (PRIME-MD), a diagnostic tool developed in the mid-1990s by Pfizer Inc. The length of the original assessment limited its feasibility; consequently, a shorter version, consisting of 11 multi-part questions - the Patient Health Questionnaire was developed and validated.
Fear of negative evaluation (FNE) or fear of failure, also known as atychiphobia, is a psychological construct reflecting "apprehension about others' evaluations, distress over negative evaluations by others, and the expectation that others would evaluate one negatively". The construct and a psychological test to measure it were defined by David Watson and Ronald Friend in 1969. FNE is related to specific personality dimensions, such as anxiousness, submissiveness, and social avoidance. People who score high on the FNE scale are highly concerned with seeking social approval or avoiding disapproval by others, and may tend to avoid situations where they have to undergo evaluations. High FNE subjects are also more responsive to situational factors. This has been associated with conformity, pro-social behavior, and social anxiety.
Empathy quotient (EQ) is a psychological self-report measure of empathy developed by Simon Baron-Cohen and Sally Wheelwright at the Autism Research Centre at the University of Cambridge. EQ is based on a definition of empathy that includes cognition and affect.
The Yale Food Addiction Scale (YFAS) is a 25-point questionnaire, based on DSM-IV codes for substance dependence criteria, to assess food addiction in individuals. The scale was released in 2009 by Yale University's Rudd Center for Food Policy and Obesity.
The 9-question Patient Health Questionnaire (PHQ-9) is a diagnostic tool introduced in 2001 to screen adult patients in a primary care setting for the presence and severity of depression. It rates depression based on the self-administered Patient Health Questionnaire (PHQ). The PHQ is part of Pfizer's larger suite of trademarked products, called the Primary Care Evaluation of Mental Disorders (PRIME-MD). The PHQ-9 takes less than 3 minutes to complete and simply scores each of the 9 DSM-IV criteria for depression based on the mood module from the original PRIME-MD. Primary care providers frequently use the PHQ-9 to screen for depression in patients.
Grazing is a human eating pattern characterized as "the repetitive eating of small or modest amounts of food in an unplanned manner throughout a period of time, and not in response to hunger or satiety cues".
The Night Eating Questionnaire (NEQ) is one of the most widely used measures for the assessment of night eating syndrome. The original NEQ was revised several times and its current version was published by Allison and colleagues in 2008. The NEQ has 14 items and responses are recorded on a five-point scale from 0 to 4 with each item having different response labels. Additional items for assessing perceived distress and functional impairment can be used but these are not included in the total score.
