Sci-fly: Een kind dat niet wil eten en een moeder die dwingt te eten: Wie beïnvloedt wie?

Kieskeurig eetgedrag komt veel voor bij jonge kinderen. Ze lusten maar een beperkt aantal producten, en iets nieuws proberen? Ho maar! Dit eetgedrag kan bij ouders voor frustratie zorgen, maar ook voor ongerustheid over de gezondheid van hun kind. Het is echter nog niet bekend waarom deze twee gedragingen aan elkaar gerelateerd zijn. Lokt het kieskeurige eetgedrag deze ouderlijke controle uit? Of worden kinderen kieskeuriger naarmate ouders meer druk uitoefenen om te eten?

Deze studie onderzocht of kieskeurig eetgedrag van kinderen gerelateerd was aan meer ouderlijke druk om te eten bij moeders, en of ouderlijke druk bij moeders op zijn beurt meer kieskeurig eetgedrag bij kinderen voorspelde. Uit de resultaten bleek beide het geval te zijn. De onderzoekers concludeerden dat moeder en kind elkaars gedrag rondom kieskeurig eten wederzijds beïnvloedden, en daarmee versterken. Hoewel ouders waarschijnlijk met goede bedoelingen hun kind dwingen om te eten, lijkt dit op langere termijn een averechts effect te hebben. Daarom zouden ouders gestimuleerd moeten worden om op een andere manier met het kieskeurige eetgedrag van kun kind om te gaan. De onderzoekers adviseerden om hier specifieke adviezen voor te ontwikkelen.

In dit Nederlandse onderzoek deden 4845 moeder-kind duo’s mee. Moeders vulden op vier momenten vragenlijsten in. Toen kinderen 1.5, 3, 4 en 6 jaar oud waren, vulden moeders vragen in over het eetgedrag van hun kind. Op 4-jarige leeftijd, vulden moeders ook een vragenlijst in naar ouderlijke druk om te eten.


  • Kieskeurig eetgedrag bij kinderen op 1.5-jarige leeftijd voorspelde meer ouderlijke druk om te eten bij moeders tweeënhalf jaar later.
  • Kieskeurig eetgedrag bij kinderen op 3-jarige leeftijd voorspelde ook meer ouderlijke druk om te eten bij moeders één jaar later.
  • Het gebruik van ouderlijke druk om te eten bij moeders op 4-jarige leeftijd (van het kind), voorspelde meer kieskeurig eetgedrag bij het kind twee jaar later.

Growing in the face of challenge: What the COVID-19 pandemic can teach us about reducing substance use?

The COVID-19 pandemic has affected everyone in one way or another. These global events can flood us with uncertainty and can challenge our world-views. Naturally, the pandemic has forced us to re-organize our life priorities – health being the number one. Most research about disaster events has focused on the relationship with negative consequences, such as negative emotions, mental health disorders (post-traumatic stress disorder (PTSD), anxiety and depression), and increases in substance use1–3. It can’t be denied that negative consequences are important and should not be overlooked. But is it all there is to it? For example, highly stressful life experiences can also bring a new sense of meaning to life. Could a life-crisis result in a new lifestyle that discourages maladaptive behaviours such as substance use?


Posttraumatic growth (PTG) describes the phenomenon in which critical life experiences result in (positive) transformation4,5. This concept does not contradict the hardships of stressful life events; it highlights the potential for positive change that can co-exist in a critical situation. To experience this growth, an individual would have to perceive a threat, an “inflection point”, in which his or her established set of schemas do not longer suffice. It goes beyond returning to a pre-crisis state, but it is about experiencing meaningful development. This idea of growth after stress is very attractive, but you may wonder whether this remains a philosophical suggestion or whether empirical studies can support the growth of vulnerable individuals amid challenging life events.

PTG is a relatively new concept in psychological research. Overall, it can be measured by five domains of growth5: a) gratitude and alteration of life priorities; b) greater relationship quality; c) increases in perception of personal strength; d) acknowledgement of new opportunities; and e) engagement in existential questions. Post-traumatic growth has been explored mainly in connection with general psychological well-being and adjustment after highly stressful life events. Not many studies have looked into the association between the mentioned domains of growth and substance use. However, there are some indications of a relationship between stressful life events, PTG, and a decrease in problematic substance use.

Some research has explored the positive impact of stressful events in substance use in at-risk populations6. For example, qualitative interviews of ex-smokers smoking have described to be “at a critical” point in their lives when they quitted 7. Furthermore, a very large study of 4569 young adults found that experiencing stressful events was associated with decreases in alcohol use mainly for dependent drinkers8. These stressful life events could have acted as a “critical transition point” for them. However, as they did not measure PTG per se, the interpretation remains speculative. Interestingly, a two-year study in adolescents at risk for maladaptive behaviours applied a PTG scale to quantify the relationship between amount of stressful-life events, PTG and substance use6. They did find that higher stressful events were associated with increased substance use in adolescence; however, those who could find positive change in life altering events were more protected against problematic alcohol and cannabis use.

Finally, some preliminary results about general COVID-19 mental health and positive appraisal supports this idea for mental health generally9. A positive evaluation of these events appear to protect against psychological distress amid the COVID-19 pandemic. Particularly, those who reported that they could learn and change for the better, both personally and as a society, preserved a good mental health during the first weeks of the European Corona lockdown. We still need to determine whether this same mechanism can apply to substance use behaviour specifically for the COVID-19 pandemic, although the described literature does provide some indications.

To summarize, our ability to learn from a specific, life-altering, event may influence how we modify unhealthy patterns (such as decreasing substance use). Yet, this stressful experience may have to provide a critical transition point, and “eye-opening” experiences for those engaged in substance use. It might not be about the accumulation of stressful life events in itself, but about how that particular event has shaken your life views and has presently impacted you. Now it may be your job to find personal meaning in this corona situation and ask yourself some tough questions!
