general self efficacy
General Self-Efficacy
  • General self efficacy- “broad and stable sense of personal competence to deal effectively with a variety of stressful situations” (Schwarzer & Luszczynska)
    • General Self-Efficacy (GSE) Scale
      • 10 questions, range 1-4 for each
      • Ex) “I can always manage to solve difficult problems if I try hard enough” (Schwarzer & Jerusalem, 1995).

    • Medication Adherence
    • Condom Use
    • Preventive Behaviors (Breast Self Examination)

  • Drinking Refusal Self-Efficacy
    • Drinking Refusal Self-Efficacy Questionnaire (DRSEQ)
  • Abstinence Self-Efficacy
    • Alcohol Abstinence Self-Efficacy Scale (AASE)
smoking cessation self efficacy
Smoking Cessation Self-Efficacy
  • Smoking Self-Efficacy Questionnaire (SSEQ)
    • Context-specific: self-efficacy varies from situation to situation
  • Relapse Situation Efficacy Questionnaire (RSEQ)
    • Predicts smoking rate: negative affect, positive affect, restrictive situations (to smoking), idle time, social-food situations, low arousal, cravings
medication adherence self efficacy
Medication Adherence Self-Efficacy
  • Used to explain adherence to regimens of:
    • Anti-retroviral medication for HIV
    • Self-injection treatment for MS
    • Epilepsy medications
    • Diabetes- Self-Efficacy for Diabetes scale
      • Insulin injections, blood glucose monitoring, dietary prescriptions, exercise
    • Hypertension
      • Medication adherence self-efficacy scale (Gbenga et al, 2003)
condom use self efficacy
Condom Use Self-Efficacy
  • Condom Use Self-Efficacy scale- describes “feelings of confidence about being able to purchase and use condoms”
detective behaviors self efficacy
Detective Behaviors Self-Efficacy
  • Breast Cancer Screening- Breast Self Examination
    • BSE Self-Efficacy scale measures intention + maintenance
  • Prostate Cancer Screening
  • Colorectal Cancer Screening
un related constructs
(Un)related Constructs
  • Self-concept- “organized knowledge of oneself”
  • Self-esteem- emotional response to self-knowledge
  • Locus of control- attribution of responsibility for outcomes
  • Self-concept of ability- “judgment of competence without reference to action”
  • Dispositional optimism- “generalized outcome expectancies”
  • Hope- agency (similar to self-efficacy) + pathways (similar to outcome expectancies)
locus of control
Locus of Control
  • Internal or external (I/E)
    • Internal control of behavior (individual)
    • External control of behavior (other forces/chance)
  • A greater internal locus of control can promote better health.
    • Similar to self-efficacy, but self-efficacy “is also behavioral and prospective” (Schwarzer & Luszczynska)
