Questionnaire: Strengths
Versatile and can be used for descriptive, exploratory, and explanatory research
Standardized
Measure a wide variety of unobservable data, for example:
o People’s preferences (e.g., political orientation)
o Traits (e.g., self-esteem)
o Attitudes (e.g., towards immigrants)
o Beliefs (e.g., about new law)
o Behaviours (e.g., smoking)
o Factual information (e.g., income)
Ideal for collecting data remotely if the population cannot be observed directly because of its size
Large sample survey may facilitate findings of small effects while analyzing multiple variables and comparative analysis of population subgroups (e.g., within-group or between group analysis).
Preferred by some respondents as they can be completed at their convenience
Economical (both time and cost)
Questionnaire Strengths for Case Study:
In relation to the case study of integrating health care aides on pediatric off service mental health units to decrease incidents of escalation in behaviour, the survey questionnaire could be utilized to gather nurse and physician feedback regarding the change in model of care. As a standardized tool, all participants would be posed the same questions in the same way. Important information could be collected regarding people’s preferences (HCAs vs. security guards), traits (general receptiveness to change), attitudes (towards unregulated health care providers), beliefs (about the new model and care provided), behaviours (their actions supporting integration of HCAs into the team), factual information (number of escalations). A large sample size could be utilized – all nurses and all physicians working on the off-service unit. Patient care wouldn’t be disrupted as the respondents could answer the questionnaire anytime (not just at work) and at their convenience, and confidentiality of the patients would be maintained (researchers not required on the unit). Questionnaires (electronic, as staff all have access to email) are also resource (time and cost) friendly.
