Intervening variables and hypothetical constructs need not be incompatible; Thorndike's hypothetical neural process could empirically be found to be the mechanism through which Hull's abstraction operates.
Intervening variables, like morale and culture, connect the management and clinical processes.
Intervening variables identified for the study were smoking, substance abuse, immunosuppressive therapy, clinical comorbidities, and prescription medications.
Over four decades, fluctuations in the sinuosity index (1.15 1.43) and vegetation cover (63%–83%) are not significantly correlated (r = 0.28, p > 0.05), suggesting that relationships between the two are mediated by intervening variables and uncertain lag times.
We analyzed the data using Structured Equation Modeling (SEM) to evaluate the strength of the hypothesized relationships, if any, among the constructs, which include Perceived Ease of Use and Perceived Web Security as independent variables, Perceived Usefulness and Attitude as intervening variables, and Intention to Use as the dependent variable.
We will evaluate the influence of contextual factors, intervention fidelity, and intervening variables on implementation and outcomes using a mixed methods approach (Table 4).
The lack of association between baseline psychopathology (phase II) and QOL and the existence of an association between concurrent psychopathology and QOL suggests that intervening variables rather than psychopathology that occurred decades earlier impacts current QOL.
Analysis of covariance (ANCOVA; factor diagnosis, intervening variables age and duration of education) demonstrated that compared with control subjects, patients with OCD displayed a significantly reduced A-GI on the left side (df = 1, 58; F = 5.65; p = 0.021) and a trend for a decreased A-GI on the right side (df = 1, 58; F = 3.26; p = 0.076).
Intervening variables (i.e., in determining intervention fidelity) are assessed from surveys of front-line staff pre- and post-intervention.
Therefore, it is very difficult to control all the possible intervening variables and they can be considered as one of the data variability sources.
An attractive possibility is that intervening variables may have discoverable physiological bases.
