2. Below is a description of a fictitious study. Read the description and then answer the questions that follow.
Brady hypothesized that the absence of socio-emotional support among the elderly results in a high level of chronic health problems and low morale. He tested this hypothesis by interviewing a sample of 250 residents of one community who were aged 65 years and older. The participants were randomly selected from a list of town residents. Brady asked a series of questions about the availability of socio-emotional supports (e.g., whether the participants lived with any family, whether they had any living children who resided within 30 minutes away, etc.). Based on responses to the various questions on social support, participants were classified in one of three groups: low social support, moderate social support, and high social support. In a 6-month follow-up interview, Brady collected information from 214 participants about the frequency and intensity of the respondents’ illnesses in the preceding 6 months, their hospitalization record, and their overall satisfaction with life. The data analysis revealed that participants in the low-support group had significantly more health problems, hospitalizations, and lower life satisfaction ratings than those in the other two groups. Brady concluded that the availability of social support resulted in better physical and mental adjustment to old age.
