attrition bias

Informed presence bias Observer bias [11] The model explained the conditions under which people will make informed dispositional versus situational attributions. While this is useful, it is important to note that even small proportions of patients lost to follow-up can cause significant bias. [31] The retraining process specifically targeted students who tended to attribute poor academic performance to external factors. in the exposure groups, or losses of different types of participants, whether at similar or different frequencies, may change the characteristics of the groups, irrespective of the exposure or intervention. Each of these biases describes a specific tendency that people exhibit when reasoning about the cause of different behaviors. Unacceptable disease bias

Building on Heider's early work, other psychologists in the 1960s and 1970s extended work on attributions by offering additional related theories. Research has also indicated that children can develop hostile attribution bias by engaging in aggression in the context of a video game. In this case, the child made an attribution of hostile intent, even though the other children's behavior was potentially benign. [22], Studies on attribution bias and mental health suggest that people who have mental illnesses are more likely to hold attribution biases. Please post a comment on our Facebook page.

Taken together, these studies provide evidence for the flexibility and modifiability of attributional biases. Measurement and Evaluation in Counseling and Development, 32, 111–118. (1967). Storms found that participants ascribed more causal influence to the person they were looking at. According to the actor-observer bias, in addition to over-valuing dispositional explanations of others' behaviors, people tend to under-value dispositional explanations and over-value situational explanations of their own behavior. An attrition rate of under 5% is usually no concern (Schulz and Grimes, 2002), while rates in excess of 20% may be cause for concern. Confounding by indication

Kelley's covariation model also led to the acknowledgment of attribution biases. This reinforces the notion that individualistic and collectivistic cultures tend to focus on different aspects of a situation when making attributions. When participants leave, it may not be known whether they continue or discontinue an intervention; there may be no data on outcomes for these participants after that time.

attrition bias. Patients are lost to follow up in almost every trial.

A dictionary of epidemiology.

Kelley used the term 'covariation' to convey that when making attributions, people have access to information from many observations, across different situations, and at many time points; therefore, people can observe the way a behavior varies under these different conditions and draw conclusions based on that context.

The need to compare like-with-like in treatment comparisons, Potential impact on estimated treatment effects of information lost to follow-up in randomised controlled trials (LOST-IT). Research has indicated that there is an association between hostile attribution bias and aggression, such that people who are more likely to interpret someone else's behavior as hostile are also more likely to engage in aggressive behavior. Participants were then asked to report their attitudes towards the writers under two separate conditions. [7][8][9], Research on attribution biases is founded in attribution theory, which was proposed to explain why and how people create meaning about others' and their own behavior. These results demonstrated that participants did not take situational factors into account when evaluating a third party, thus providing evidence for the fundamental attribution error.

Rather, the theoretical reformulation posits that the way people explain behavior depends on whether or not it is intentional, among other things. For example, studies have implemented attributional retraining to help students have more positive perceptions of their own academic abilities (see below for more details). Ascertainment bias Comments? Mimicry bias Psychologist Fritz Heider first discussed attributions in his 1958 book, The Psychology of Interpersonal Relations. Following the conversation, participants were asked to make attributions about the conversationalists. One way to determine whether losses to follow-up can seriously affect results is to assume a worst-case scenario for the outcomes in those with missing data and look to see if the results would change. One major proponent of this view was Yale psychologist Michael Storms, who proposed this cognitive explanation following his 1973 study of social perception.

Starting time bias Techniques for preventing losses follow-up include ensuring good communication between study staff and participants, accessibility to clinics, effective communication channels, incentives to continue, and ensuring that the study is of relevance to the participants. Some participants viewed the conversation while facing Actor One, such that they were unable to see the front of Actor Two, while other participants viewed the conversation while facing Actor Two, obstructed from the front of Actor One.

A review of the literature on intergroup attribution biases noted that people generally favor dispositional explanations of an in-group member's positive behavior and situational explanations for an in-group's negative behavior.

A study of psychosocial factors among patients with cardiac conditions showed that those who fully completed the study differed in clinical and psychosocial features from those who dropped out before the study ended. Allocation bias According to this error, when someone makes attributions about another person's actions, they are likely to overemphasize the role of dispositional factors while minimizing the influence of situational factors. Keep follow-up interviews as brief as possible. These criticisms of the attribution model reveal that the theory may not be a general, universal principle.[34]. Unequal loss of participants from study groups in a trial. Effects of behavior: People are more likely to make a correspondent, or dispositional, inference when someone else's actions yield outcomes that are rare or not yielded by other actions. [1] He also explained that this tendency was rooted in a need to maintain a positive self-concept, later termed the self-serving bias. There is high consistency when a person almost always behaves in a specific way. In his work on attribution theory, Fritz Heider noted that in ambiguous situations, people make attributions based on their own wants and needs, which are therefore often skewed. Trial attrition study group.

editors. For example, correlations may be found where there are none, or important correlations may be missed entirely. Low consistency is when a person almost never behaves like this. A systematic review assessed the reporting, extent, and handling of loss to follow-up and its potential impact, on treatment effects in randomised controlled trials published in the five top medical journals, The authors calculated the percentage of trials in which the relative risk would no longer be significant when participants loss to follow-up varied. Analysis of those still in the trial showed no difference in the quality of life. The theory was formed as a comprehensive explanation of the way people interpret the basis of behaviors in human interactions; however, there have been studies that indicate cultural differences in the attribution biases between people of Eastern, collectivistic societies and Western, individualistic societies. In: Catalogue Of Bias 2017.  https://catalogofbias.org/biases/attrition-bias/, GET-IT provides plain language definitions of health research terms, Select a biasAdmission rate bias Novelty bias Social desirability: People are more likely to make a correspondent inference when an actor's behavior is socially undesirable than when it is conventional. Centripetal bias Apprehension bias Attrition bias is a systematic error caused by unequal loss  of participants from a randomized controlled trial (RCT).

However, the results may not necessarily be biased, despite different drop-out rates in the groups. Biases of rhetoric While this is useful, it is important to note that even small proportions of patients lost to follow-up can cause significant bias. Substantial loss to follow-up and missing data in arthroscopy national registries: a systematic review.

Consensus: The extent to which other people behave in the same way.

[8] More specifically, hostile attribution bias has been associated with reactive aggression, as opposed to proactive aggression, as well as victimization. These same findings were replicated in a study done by Michael Morris[33] where an American group and a Chinese group were asked their opinions about the killings perpetrated by Gang Lu at the University of Iowa. Additionally, some scientists believe that attributional biases are only exhibited in certain contexts of interaction, where possible outcomes or expectations make the forming of attributions necessary. Publication bias If this method doesn’t change the study’s conclusions, the loss to follow-up is likely not a threat to the study’s validity.

J Clin Epidemiol. In 1965, social psychologists Edward E. Jones and Keith Davis proposed an explanation for patterns of attribution termed correspondent inference theory. Hypothetical Bias They explained that certain conditions make us more likely to make a correspondent inference about someone's behavior: Soon after Jones and Davis first proposed their correspondent inference theory, Harold Kelley, a social psychologist famous for his work on interdependence theory as well as attribution theory, proposed a covariation model in 1973 to explain the way people make attributions.
