The Beck Hopelessness Scale (BHS) is a 20-item self-report instrument developed by Aaron Beck and colleagues (1974) to measure the degree of hopelessness and pessimism about the future in adolescents and adults. It is grounded in Beck's cognitive theory of depression and suicide and is widely used in clinical, psychiat
Case law analysis is a systematic method for examining judicial decisions to identify binding legal rules, evolving doctrines, and interpretive trends. Rooted in the common law tradition of stare decisis, it requires the researcher to locate the ratio decidendi — the binding reasoning — of each decision, distinguish it
Comparative doctrinal legal research systematically identifies, expounds, and compares the legal rules, principles, and doctrines governing the same problem across two or more jurisdictions. It combines the internal rigour of doctrinal analysis — mapping the authoritative sources of a single legal system — with the ext
Comparative legal analysis is a structured research method that examines how two or more legal systems — whether national, regional, or supranational — address a common legal problem. By placing rules, doctrines, and judicial decisions side by side, researchers identify convergences, divergences, and the underlying soc
Crime linkage analysis is a forensic method that determines whether a series of crimes were committed by the same offender based on behavioral and modus operandi (MO) similarities. Developed systematically by Craig Bennell and colleagues in the early 2000s, crime linkage applies statistical and similarity-matching tech
Critical case law analysis applies the theoretical tools of Critical Legal Studies (CLS) to the examination of judicial decisions. Rather than accepting legal reasoning at face value, this approach interrogates how courts construct legal arguments, whose interests those arguments serve, and how ideological commitments
Critical doctrinal legal research combines traditional black-letter legal analysis — systematically mapping the rules, principles, and doctrines found in statutes and case law — with the evaluative lens of critical legal theory. Rather than treating legal doctrine as a neutral or self-contained system, it interrogates
Doctrinal legal research is the foundational methodology of legal scholarship. It systematically identifies, reads, and analyses authoritative legal sources — statutes, case law, constitutional texts, and regulations — to describe, explain, and critique the content and internal logic of legal doctrine. By working withi
Evaluation-focused legal content analysis is a systematic method for examining legal texts — statutes, regulations, court decisions, contracts, or policy documents — with an explicit evaluative purpose: to assess whether and how well legal instruments achieve specified goals, standards, or values. It combines the struc
The Forensic Likelihood Ratio (LR) is a Bayesian framework for quantifying the weight of forensic evidence relative to two competing propositions — typically the prosecution and defence hypotheses. Formally developed and systematised by Colin Aitken and Franco Taroni in their 2004 Wiley monograph, the LR expresses how
Geographic profiling is a spatial analysis method used in forensic investigation to locate offenders based on the locations of their crimes. Developed by David Canter in 1994, it combines geostatistics, probability theory, and crime pattern analysis to identify high-probability crime origin zones. The method has been w
The HCR-20v3 is a structured professional judgment framework developed by Douglas, Hart, and colleagues for the assessment of risk for violence among adolescents and adults in mental health, criminal justice, and forensic settings. Published in 2013, it represents the third version of one of the most widely validated r
Legal content analysis applies the systematic procedures of content analysis to legal texts — statutes, regulations, judicial opinions, treaties, and legal commentaries — in order to identify patterns, themes, and trends across a corpus of legal material. It bridges qualitative legal scholarship and quantitative social
Legal judgment prediction is a machine learning approach that forecasts court decisions and judicial outcomes based on case features, legal precedent, and judicial characteristics. Pioneered by Daniel Katz and colleagues in 2017 with their celebrated U.S. Supreme Court prediction model, this method applies supervised l
Longitudinal comparative legal analysis examines how legal rules, doctrines, or institutions develop and diverge across two or more legal systems over an extended period. By combining the spatial dimension of comparative law with the temporal dimension of longitudinal research, it captures not just differences between
The Level of Service Inventory-Revised (LSI-R) is a 54-item assessment instrument developed by Andrews and Bonta (1995) to measure offender risk level and criminogenic needs (dynamic risk factors related to criminal behavior) in criminal justice populations. It is grounded in the Risk-Need-Responsivity (RNR) model of o
The Novaco Anger Scale and Provocation Inventory (NAS-PI) is a comprehensive self-report assessment instrument developed by Raymond Novaco (2003) to measure dispositional anger and anger provocation in adolescents and adults. It integrates cognitive-behavioral theory of anger and emotional regulation, serving clinician
Network analysis of case law applies graph-theoretic and network science methods to study the structure and dynamics of legal precedent systems. Developed systematically by James Fowler and colleagues in 2011, this method treats legal citations as directed edges in a network where nodes represent court decisions and ed
The Psychopathy Checklist Screening Version (PCL-SV) is a 12-item assessment tool developed by Hart, Cox, and Hare (1995) to screen for psychopathic personality traits in adolescents and adults. It is a brief alternative to the full 20-item Psychopathy Checklist-Revised (PCL-R), designed for rapid screening in correcti
Risk Terrain Modeling (RTM) is a geospatial crime prediction method that identifies high-risk locations by analyzing environmental and geographic features that attract or facilitate crime. Developed by Joel Caplan, Lichen Kennedy, and James Miller in 2011, RTM bridges environmental criminology theory with geographic in
The Structured Assessment of Protective Factors for Violence Risk (SAPROF) is a 17-item structured professional judgment tool developed by de Vogel, de Ruiter, Bouman, and colleagues (2012) to identify protective factors and strengths in individuals undergoing violence risk assessment. It complements risk assessment in
The Structured Professional Judgment (SPJ) framework represents a contemporary approach to forensic risk assessment that synthesizes clinical judgment with empirical evidence of risk factors. Rather than producing a numerical score, SPJ guides clinicians through systematic evaluation of case-specific evidence to arrive
The Suicide Probability Scale (SPS) is a 36-item self-report instrument developed by John Cull and William Gill (1990) to assess suicide risk, hopelessness, suicide ideation, negative self-evaluation, and hostility in adolescents and adults. It provides a multidimensional profile of suicide-related cognitions and emoti
The Static-99R is an actuarial risk assessment instrument designed to estimate the likelihood of sexual recidivism among adult male sex offenders. Originally developed as the Static-99 by Hanson and Thornton (2000) and revised in 2009 as the Static-99R by Hanson, Helmus, and Thornton, it remains one of the most widely
The Violence Risk Appraisal Guide (VRAG) is an actuarial instrument developed by Harris, Rice, and Quinsey (1993) to estimate the probability of violent recidivism among adult male offenders released from forensic psychiatric hospitals. It represents one of the earliest empirically validated violence prediction tools a
