Exploring the Effects of Negative Affect on Mental Health

We experience a wide range of feelings that can have different impacts on us. These feelings can range from positive to negative, and each has its own unique effect on our emotions and well-being. While some feelings may bring a sense of calm and tranquility, others may activate and stimulate us.

Negative affect is a term used to describe a specific category of feelings that are commonly associated with emotional distress. It encompasses a range of emotions that can cause discomfort and unease. These negative feelings can manifest as sadness, anxiety, anger, frustration, or any other form of emotional distress.

Causes of Negative Affect

Negative affect is a biologically adaptive response to stress encountered in the environment. Our conscious experience of negative emotions may be tied to the activation of the sympathetic nervous system. All the biological changes such as increased heart rate, rising blood pressure, and tightening muscles, create a feeling affect, which from past experience we most likely associate with a threat.

Once these feelings break though to consciousness, we interpret the feeling as an emotion (anger, fear, frustration, etc.). Usually, the context surrounding the activation of the sympathetic nervous system is instrumental in defining the emotion. Sometimes, we can’t find an immediate cause, so we unconsciously target something in the environment. This is known as affective realism.

For example, we may unintentionally cut someone off on the freeway. As they pass, they yell at us and point a shiny silver object at us. Our bodies perceive the danger, the sympathetic nervous system readies muscles and organs to fight or flee. We are experiencing negative affect. Perhaps, fear at first, followed by anger.

Loss and Negative Emotions

When we lose someone we love, our bodies react, altering the levels of stress-related opioids in the brain and increasing levels of inflammatory proteins in the blood (Brady, 2016). These changes, just like the activation of the sympathetic nervous system creates a feeling affect that we translate into an emotion once it enters consciousness. Again, based on surrounding circumstances, we interpret the feeling affect. “I am sad.”

T. Franklin Murphy explains that, “Feeling affects draw conscious attention to the feeling incident and we interpret the feeling, giving emotion labels that categorize and characterize the experience with greater granularity” (Murphy, 2021). Negative affect is caused by our perception of outside events. Our perception is influenced by interpretation of observation strongly biased from past histories, and level of arousal which is determined by the significance of the threat and our biological makeups. 

Feeling affects are experienced in connection to both the valence and level of arousal, and consciously experienced as pleasant or unpleasant, based on our interpretation of the feeling incident. 

Trait  Negative Affect

“Trait negative affect represents the tendency to experience these negative mood states” (Miller et al., 2012). A person that experiences high levels of negative affect may, perhaps, have a biological propensity to be quickly aroused by perceived threats. Some research suggests that this may be caused by a negative explanatory style, also known as attribution style. 

Murphy describes the negative attribution style as “a pessimistic explanatory style, explaining negative events as permanent, pervasive and personalized and positive events as passing, limited in scope and generalized” (Murphy, 2022).

High levels of Negative Affect Associated with Depression

Individuals suffering from depression typically experience abnormal patterns of frequent and lingering emotional disturbances. “Depressive symptomatology is centrally characterized by increased levels of negative affect combined with decreased levels of positive affect” (Dejonckheere et al., 2018).

Bipolarity of  Negative and Positive Affect

Traditionally, we view negative and positive affect states on opposite poles. Indeed, this view is cognitively reasonable. When we are in a bad mood, we have no positive affect; and when we are in a good mood, we have no negative affect. However, some research over the last several decades challenge this view, suggesting that both positive and negative emotions operate independent of each other.

In 1995, the National Advisor Mental Health Council advised:

“While one would ordinarily think that positive and negative emotions are opposites, apparently this is not the case” (Russell & Carroll, 1999).

Whether positive and negative emotions act independently or as bipolar opposites continue to be a matter of debate.

Much of our subjective well-being depends on how positive and negative emotions interrelate with each other differs.

For instance, some empirical evidence suggests that people “differ in the extent to which they experience positive and negative affect rather independently or as bipolar opposites.” Dejonckheere and colleagues examined how this difference in whether an individual experienced positive and negative independently or as polar opposites correlated with emotional well-being and depressive mood states.

Their findings support the theory that depressive symptomatology includes “the experience of positive affect and negative affect becoming more mutually exclusive, with negative feelings implying a lack of positive feelings and vice versa, reflected in a more negative relation between the two” (Dejonckheere et al., 2018).

Emotional Regulation

Research has discovered a link between persistent and intense negative emotions and the tendency to use maladaptive, avoidant coping strategies to regulate the negative affect (Miller et al., 2012).

Roy Baumeister explains the link between negative affect and adverse outcomes by positing that “one’s proneness to experiencing negative affect increases one’s favoring of immediate and perhaps maladaptive responses to alleviate negative mood states (Miller et al., 2012, p. 1318).

Associated Concepts

• Neuroticism: This is a personality trait characterized by a tendency to experience negative emotions. People high in neuroticism are more likely to experience negative affect.
• Mood Disorders: Negative affect is a significant component of mood disorders like depression and bipolar disorder, where individuals often experience prolonged periods of negative emotions.
• Anxiety Disorders: These disorders are associated with negative affect, particularly emotions like fear, nervousness, and worry.
• Stress and Coping Theory: The experience of stress is closely linked to negative affect, and how individuals cope with stress can influence the intensity and duration of negative affect.
• Affective Flattening: This refers to a reduction in the range and intensity of emotional expression, including facial expressions, voice tone, and gestures.
• Positive and Negative Affect Schedule (PANAS): This is a psychometric scale used to measure the positive and negative affect. It’s often used in psychological research to assess mood.
• Cognitive Theories of Emotion: These theories suggest that thoughts and other cognitive processes play a crucial role in the formation of emotions, including negative affect.
• Behavioral Medicine: Negative affect has been linked to physical health outcomes, such as cardiovascular disease, and health behaviors like smoking and eating habits.

A Few Words by Psychology Fanatic

In conclusion, the intricate relationship between negative affect and mood disorders highlights the need for ongoing research and understanding. As we navigate through various emotional landscapes, it becomes increasingly vital to recognize how our feelings can shape not only our mental health but also our overall well-being. By delving deeper into the mechanisms behind negative affect, we open doors to more effective interventions and coping strategies that empower individuals to transform their experiences of distress into opportunities for growth.

Ultimately, fostering a supportive environment is essential in mitigating the effects of negative emotions. Embracing healthy coping mechanisms—such as mindfulness practices, social connections, and engaging in activities that promote positive experiences—can significantly alter one’s emotional trajectory. As we strive for psychological balance, let us remain committed to exploring new avenues of knowledge while encouraging each other on this journey toward emotional resilience and fulfillment.
