Measurement of source credibility has been a concern of the Communication discipline for over 40 years. The first multidimensional measure appeared in the Communication literature in 1966 (McCroskey, J .C., Scales for the measurement of ethos, Speech Monographs, 33, 65-72) and provided scales measuring competence and trustworthiness. Many other studies were conducted over the next 30 years. This Source Credibility Measure is the most complete measure and includes scales for three dimensions: competence, trustworthiness, and goodwill/caring. These are measures of constructs which are...
Immediacy, particular non-verbal immediacy has received increasing attention from communication scholars. In general, this research indicates that communicators who engage in non-verbal immediate behaviour with others are seen by those others in a more positive way. This Nonverbal Immediacy Scale-Observer Report (NIS-O) addresses problems of previous scales which measure this.
The Non-verbal Immediacy Scale-Self Report (NIS-S) is based on the immediacy of people in relation to communication. This is the most up-to-date measure of nonverbal immediacy as a self-report. Since the purpose was to develop a measure that could be employed either as a self-report or as an other-report, some items from the measure were drawn from previously used measures.
This measure was developed as a part of a continuing research program investigating the effects of systematic desensitization on communication apprehension. The Personal Report of Public Speaking Anxiety Scale (PRPSA) is an excellent measure for research which centers on public speaking anxiety, but is an inadequate measure of the broader communication apprehension construct.
This Shyness Scale (SS) measure is also referred to as the McCroskey Shyness Scale. It was developed to obtain individual's self-report of their shy behavior. Unlike many shyness scales that have been developed in the field of Psychology, this scale does not confound communication apprehension with shy behavior. These are two very different constructs and adding items from both provide an uninterpretable score. Communication apprehension relates to fear and/or anxiety about communicating. Willingness to Communicate (WTC) relates to an orientation to initiate communication. Shyness relates...
Socio-communicative style refers to others' perception of a communicator's assertiveness and responsiveness behaviors. The SocioCommunicative Style Scale (SCS) is designed to measure the perceptions of these behaviors. Generally, these perceived behaviors are uncorrelated. These are two of the three components of the SCS construct. The third component is variously labeled as "versatility" or "flexibility." This third component is best measured by the "Cognitive Flexibility" scale.
Sociocommunicative orientation refers to an individual's perception of how assertive and responsive he/she is. This Socio-Communicative Orientation Scale (SCO) is designed to measures these orientations. Generally, these orientations are either totally uncorrelated or only marginally correlated (r < .30). These are two of the three components of the SCO construct. The third component is variously labeled as "versatility" or "flexibility." This third component is best measured by the "Cognitive Flexibility" scale.
The Situational Communication Apprehension Measure (SCAM) was developed to provide and instrument which could measure state CA in any context. This is a self-report instrument which can apply to how a person felt in any recent communication event (the closer in time between the event and completion of this instrument, the more valid the measure will be).
Self-report scales assessing relationship-specific incentive and threat sensitivity were created. The Relationship Incentive and Threat Sensitivity Scales (RITSS) was developed to assess individual differences in incentive and threat sensitivity that are specific to the context of intimate relationships. It has been used in only a little research thus far.
