AB  - The aim of this study was to investigate the predictors of burden for informal 
      caregivers of patients with dementia. Based on a multidimensional approach of the 
      optimism model proposed by Palenzuela, we assessed the moderating role of 
      generalized expectancies of control (GEC) between caregiver stress and burden. A 
      total of 130 patients with dementia and their main family caregivers were 
      assessed from different rural areas of the province of Salamanca (Spain). 
      Patients with dementia underwent a protocol to assess dementia stage, 
      cognitive-functional impairment and behavioural symptoms. Meanwhile, the 20-item 
      Battery of Generalized Expectancies of Control Scales of Palenzuela was completed 
      by the family caregivers. Clinical variables of patients with dementia 
      (progression and behavioural disorders) and GEC (success, self-efficacy, 
      contingency, helplessness and luck) were considered as potential predictors of 
      burden in the hierarchical regression analysis. The Zarit Burden Interview (ZBI) 
      Scale was used as an outcome measure. The results indicated that the clinical 
      variables could not predict burden in caregivers significantly; however, beliefs 
      in personal abilities (self-efficacy) and internal locus of control (contingency) 
      explained up to 32% of the variance in the ZBI scores. Family caregivers with 
      high expectancies of self-efficacy and contingency are less vulnerable to stress. 
      This research supports a base for interventions with informal caregivers and 
      further study.
