Data extraction

Using a predefined data extraction form, you will extract relevant information from selected studies, including study design, sample characteristics, assessment tools/methods, key findings, and implications for violence risk assessment.

Data Extraction Tool for Systematic Literature Review on Predictive Validity of Violence Risk Assessment Tools

• Citation Details (title, authors, year etc)
• Study Objectives
  • Objective/Hypothesis: (Briefly state the main objective or hypothesis of the study)
• Study Design
  • Design Type: (e.g., longitudinal, retrospective analysis, cross-sectional)
  • Study Period: (Start and end dates of the study)
  • Setting: (e.g., hospital, community, correctional facility)
• Population and Sample
  • Population Description: (Characteristics of the population studied, e.g., age, gender, clinical condition)
  • Sample Size: (Total number of participants)
  • Inclusion Criteria: (Criteria for including participants in the study)
  • Exclusion Criteria: (Criteria for including participants in the study)
• Risk Assessment Tool
  • Tool Name: (Name of the risk assessment tool being evaluated)
  • Tool Description: (Detailed description of the tool, including components and scoring system)
  • Administration Method: (How the tool was administered, e.g., self-report, clinical interview)
  • Who conducted the risk assessment? (Clinician/Research/Practitioner)
• Outcomes
  • Primary Outcome: (Main outcome the tool is supposed to predict, e.g., incidents of violence)
  • Follow-Up Period: (Length of time participants were followed to observe outcomes)
• Statistical Analysis
  • Analysis Methods: (Statistical techniques used to evaluate predictive validity, e.g., ROC curve, AUC, sensitivity, specificity)
  • Confounding Factors: (Any adjustments made for confounding variables)
• Results
  • Predictive Accuracy:
    • AUC (Area Under the Curve): (Value and confidence interval)
    • Subgroup Analysis: (Results of any subgroup analyses, e.g., based on age, gender)

Synthesis and analysis

Based on the extracted data, you'll synthesize findings across selected studies, identifying common themes, discrepancies, gaps in the literature, and implications for practice, policy, and future research in violence risk assessment. (Information from Canvas.)
