Presentation Overview Origins and history of Q Method Differences between ‘Q’ and ‘R’ methods and the q-sort What Q means by ‘subjectivity’ Participant and sample selection Data analysis with PQMethod Factor interpretation Summary Questions
Origins of Q Methodology Conceived by William Stephenson (pictured), who had Ph.D.s in both physics and psychology Assistant to Charles Spearman, pioneer of factor analysis ‘Technique of factor analysis.’ Nature, 1935, 136(3434), p.297
Q Sort Typically statements written on cards ‘Forced distribution’ to a standard curve
Persons ‘R’ Methods Simple data matrix Pearson’s ‘r’ r = 0.80 r = r = 0.00 Variables 1234m a ax1ax2ax3ax4axm b bx1bx2bx3bx4bxm c cx1cx2cx3cx4cxm d dx1dx2dx3dx4dxm n nx1nx2nx3nx4nxm
Operant Subjectivity According to Watts (2011: 39) an ‘operant’ behaviour possesses two qualities: 1. an operant is produced and emitted naturally, without need for special training or any other form of artificial induction. 2. an operant is defined by the relationship it establishes with, and the impact it makes upon, the immediate environment.
Operant Subjectivity Subjectivity is NOT some part of our consciousness “It is not ‘inside’ us” (Watts, 2011: 39), Q is not a kind of phenomenological account An expression of operant subjectivity can be recorded in a ‘Q-sort’
Q Method Participants are called the ‘p-set’ Who are they? How many? Statement sample is called the ‘q-set’ Concourse theory – the ‘universe’ of possible statements Select a representative sample from the concourse – the q-set
Factor interpretation Factor Scores -- For Factor 1 # Statement Z-SCORES 3 Organic is beneficial to biodiversity Org farming returns material to the soil For org to be fair, animals need well-being Fertilizers shall not harm the environment Eating food grown in a particular way No consistent scientific evidence of better nutrition Animal health on org not necessarily better No nutritional differences between org and conv There are no safety differences between org and conv An animal has good welfare if not diseased or ill
Q-Summary Measures expressions of subjectivity Suited to exploratory, small n studies Q-bie, q-munity… Kent State listserv just turned 22!
