incorporates the different ways clinicians talked about control, including ways they exercised authority over patients (clinician control) as well as the perceived choices patients make (patient control) in controlling a disease (disease control).
The univariate results showed significant effects of perceived choice for the VAS (P<0.01), the EuroQol (P=0.02) and for HADS depression (P=0.05).
The interaction effect of perceived choice and having experienced chemotherapy pointed in the same direction for all QoL instruments, indicating that, within the group of patients who had perceived a treatment choice, not being treated with chemotherapy was related to lower current QoL.
And the depth of exasperation in the public at large places at risk a mature and responsible response to a perceived choice between the lesser of two evils, the quality of the opposition notwithstanding.
In the patient group who had not been treated with chemotherapy, the overall effect of perceived choice reached borderline significance (P=0.07).
To investigate this interaction effect in more detail, we repeated the analysis using simple main effects (perceived choice within chemo/no chemo group) and again including age as a covariate.
The voting public, in turn and especially in the middle and among independents, will be faced with a perceived choice between bad and awful, under a miasma of advertising that denigrates the entirety of American politics.
The conceptual framework for the intervention targeted the social environment (perceived autonomy, perceived social support, participation, fun), cognitive mediators (perceived choice, self-efficacy, and relatedness/belongingness), and motivational orientation (intrinsic motivation, commitment, positive self-concept).
In the study by Mandelblatt et al (2003), the potential impact on QoL of an interaction effect between treatment undergone and perceived choice was not assessed.
Furthermore, Polsky et al (2002) concluded that perceived choice was related to better QoL measured by means of the VAS (P=0.03).
