description | AIMS: To test internal consistency and factor structure of a brief instrument called Trying to Quit smoking. BACKGROUND: The most effective treatment for patients with chronic obstructive pulmonary disease is to quit smoking. Constant thoughts about quitting and repeated quit attempts can generate destructive feelings and make it more difficult to quit. DESIGN: Development and psychometric testing of the Trying to Quit smoking scale. METHODS: The Trying to Quit smoking, an instrument designed to assess pressure‐filled states of mind and corresponding pressure‐relief strategies, was tested among 63 Swedish patients with chronic obstructive pulmonary disease. Among these, the psychometric properties of the instrument were analysed by Exploratory Factor Analyses. RESULTS: Fourteen items were included in the factor analyses, loading on three factors labelled: (1) development of pressure‐filled mental states; (2) use of destructive pressure‐relief strategies; and (3) ambivalent thoughts when trying to quit smoking. These three factors accounted for more than 80% of the variance, performed well on the Kaiser‐Meyer‐Olkin (KMO) test and had high internal consistency. |
