Lecture 2: Measuring Quality of Life, Happiness and Subjective Wellbeing


Psychological research is prized on the validity and reliability of objective and subjective assessments. These methods aim to operationally define complicated constructs and pave the way for future research (Billington, Landon, Krageloh, & Shepherd, 2010)

Objective and Subjective Assessment


Objective assessment is devoid of personal and emotional prejudices due to the observable materials (e.g income and education level) studied by researchers.  In contrast, subjective measurements rely on the perceptions, judgements and unobservable phenomena (e.g thoughts, feelings, beliefs, attitudes and preferences) of individuals. Even though both approaches cannot be merged, I have understood that the unique qualities of each can assess varying dynamics of the socio-economic and individual measures of QOL, authentic happiness and SWB. 

WHOQOL

The World Health Organization Quality of Life (WHOQOL) scale is a subjective assessment that attempts to balance the rigidity of biomedical approaches and self-perceptions of patients and clients. Initially I wondered how this would apply cross-culturally; however, Rex Billington provided very efficient examples of how this barrier is overcome with multiple (accurately) translated versions. I can see how this could be a problem if the 4 domains (i.e physical health, psychological, social relations and environment) and the facets of each could easily be lost during an English to Hindi translation. The domains are also understood differently in these cultures due to the individualistic (New Zealand) and collectivist (Indian) social structures. It would be interesting to note the influence of societal structures on people's responses. 

The latter aspects of the lecture comprised of other assessments (i.e Panas and Ryff) that varied in terms of their validity and reliability but highlighted the importance of these two components nonetheless. These examples illustrated the relevance of precise definitions for the general population by avoiding psychological jargon that might hinder the subjective responses of test-takers.

Classroom Activity: WHOQOL-BREF

The applicability of the WHOQOL to clinical settings sparked a further interest in its qualities which became evident after we personally conducted the WHOQOL BREF. Having reflected on the domain-specific questions, it became clear how this 26 item tool could operationally define one’s QOL. The questions were easy to answer (due to the likert scale responses) and portrayed each domain accordingly. The 10 minute response time allowed for quick reflection of each statement. The challenge was maintaining a  pre-test two week perspective of the applicable items. It was difficult when past experiences almost hindered each subjective response, therefore a great deal of concentration was needed to overcome this barrier and answer effectively.

2nd attempt at WHOQOL-BREF with a 50 minute response time


I volunteered to take the assessment a second time to assist an AUT student who was analysing the effect of varying response times and the quality of responses that resulted. I was part of the 50 minute group. Surprisingly, my responses had varied since I’d last taken the test due to the lengthened time in which to answer each item. This allowed us to thoroughly examine each statement and analyse the underlying variables formed the final response. It was also easier to limit my thoughts within the two week span because of the understanding that there was lots of time to spare. I was able to reflect on the test multiple times and still have half an hour left. Therefore, during the focus group it was necessary to suggest a shorter response time because 50 minutes was too long. A 20-30 minute span may have been more appropriate to achieve the outcome the researcher was hoping for.
